Answer 1

Opposite/ hypotenuse

Question 2

Cos

Answer 2

Adjacent/ hypotenuse

Question 3

Tan

Answer 3

Opposite/ adjacent

Question 4

Steps for finding a resultant vector:

Answer 4

1. Find sin for y and cos for X of both vectors for
2. Add the y Values together, add the X values together
3. Find theta (angle/ sand function tan) of the y values together divided by the X values together
4. Pythagorean X and Y values to find a squared
   any time angle value is negative, add 180 to it

Question 5

Differentiation

Answer 5

The process to find the time derivative of a variable
Ex) finding velocity based on a position/ time graph
-finding accel based on velocity/ time graph
Derivative is the slope of a graph

Question 6

Integration

Answer 6

The process to find the time integral of a variable
Ex) finding position based on a velocity/ time graph
-finding velocity based on an acceleration/ time graph
Integral is the area under a curve
