 +**Steps to find derivatives as limits:**
 +
 +  - Identify the form of the derivative first (look at the image above)… is it form a? b? c?

 +
 +**Continuity**
 +
 +A function f is continuous at “c” if:
 +
 +  * The value exists- The value of the function is defined at “c” and f(c) exists
 +
 +  * The limit exists - The limit of the function must exist at “c”
 +    * The left and right limits must equal
 +
 +  * Function=limit. The value of the function at “c” must equal the value of the limit at “c”
 +
 +**Discontinuity**
 +
 +  * **Removable** → discontinuity at “c” is called removable if the function can becontinuous by defining f(c)
 +
 +  * **Non-removable** → discontinuity at “c” is called non-removable if the function cannotbe made continuous by redefining f(c)
 +
 +**Differentiability**
 +
 +**In order for a function to be differentiable at x = c:**
 +
 +  * The function must be continuous at x = c
 +
 +  * Its **left and right** derivative must equal each other at x = c

 +  * **Vectors**
 +    * Vectors are quantities that have both a magnitude and direction
 +    * Vector functions are similar to parametric functions because they describe the
 +motion of a particle on a plane
 +    * Vector functions have similar relationships between position, velocity, and
 +acceleration as we’ve seen earlier.
 +      * If a vector function P = position of a particle, then the derivative of P gives
 +you velocity, and the derivative of velocity gives you the particle’s
 +acceleration
 +        * Both x(t) and y(t) have to be differentiable for the vector function
 +to be differentiable as well
 +        * To find speed of a vector function, take the magnitude of the
 +velocity vector function
 +          * The magnitude of a vector function = $\sqrt{x^2+y^2}$
 +    * Denotation of vectors:
 +    * {{:pasted:20240410-223144.png}}
 +      * ‘i’ and ‘j’ are the unit vectors in the x and y directions
 +      * x(t) and y(t) are real valued functions of the variable ‘t’
 +    * Ex. (from Saxon Calc BC book): 
 +    * {{:pasted:20240410-223210.png}}
 +    * Integrating vector valued functions:
 +      * Similar to how you take the derivative of vector valued functions by
 +differentiating x(t) and y(t), and leaving the ‘i’ and ‘j’, to find the integral of vector-valued functions, integrate the real-valued functions and leave
 +the ‘i’ and ‘j’
 +      * Integrating a velocity vector gives you the displacement of the particle
 +over the interval of time, and integrating a speed vector gives you the total
 +distance travelled by the particle in that interval.

 +           * In this case, it takes from 0 to 2𝜋for “r” to be drawn completely, which is why those are the limits
 +     * Finding the area of a region bounded by 2 polar curves:
 +       * A = $\int_a^b \frac{1}{2}(r_2^2-r_1^2)d\theta$ with $r_2(\theta) > r_1(\theta)$ 
 +       * Ex. (from Princeton book): find the area inside the circle r = 4 and outside of the curve r = 4 - cos𝜃(the shaded region in the graph below)
 +       * {{:pasted:20240410-223811.png}}
 +       * 1) To find the limits of the integral, set the two equations equal to each other, and solve for 𝜃→ 4 = 4 - cos𝜃 = cos𝜃 = 0 at 𝜃= -𝜋/2 and 𝜋/2

 +  * Difference between sequences and series:
 +    * $a_n$ = sequence
 +    * S = $\Sigma_{n=1}^\infty a_n$ = series
 +    * Sequences are lists of the terms, whereas series are lists of the addends of the series. 
 +      * Series: to find the second term of the series, you ADD $𝑎_1$ and $𝑎_2$ together
 +        * This is known as partial sums → 2nd partial sum = $S_2 = a_1 + a_2$
 +          * nth partial sum = the sum of the first n terms of the series
 +      *** Convergence/Divergence:**
 +        * A series converges only if the SEQUENCE OF PARTIAL SUMS (𝑆𝑛) converges to a finite number. If it doesn’t converge, then it diverges.

 +      * Alternating series for convergence:

 +      * Absolute convergence:
 +        * If an alternating series converges after taking the absolute value of the series function, then that series is said to converge absolutely

 +      * **Conditional convergence:**
 +        * If an alternating series converges, and does NOT converge absolutely, then it’s said to converge conditionally
 +        * An alternating series that conditionally converges must follow these conditions:

 +    * **Radius and interval of convergence of power series:**
 +    * {{:pasted:20240410-230929.png}}
 +            * You have to check the endpoints of the interval to see if the function converges at the endpoints! If it does converge at an endpoint, place the interval in brackets, and if not, place the interval in parentheses.
 +              * If it converges at 1 endpoint and not the other, denote it like this: [a,b) or (a,b], with the bracket indicating convergence at that endpoint
 +          * **Radius of convergence: **
 +            * Similar to how the radius of a circle describes the length from the outer edge of the circle to the centerpoint, the radius of convergence describes the distance between the midpoint and the endpoint of the interval of convergence.
 +            * In the example above, the interval of convergence was [-1,1]. Thus, the radius of convergence is 1, since the midpoint of that interval is 0, and the distance between 0 (the midpoint) and 1 (the endpoint) is 1.
