Answer:
- sin = √(1 -cos²)
- tan = (√(1 -cos²))/cos
Step-by-step explanation:

_____
If you draw a triangle with a hypotenuse of 1 and an "adjacent" leg of "cos", then using the Pythagorean theorem, you can see that the "opposite" leg will be √(1-cos²) and the tangent will be (√(1-cos²))/cos. Whether or not you're allowed to draw such a triangle on paper, you can certainly do it in your mind.
If you plug in the x and y values for the points (X,Y).
Then you are able to solve for the equation by seeing whether or not it equals the Y value.
Ex. Solving 9a.
Step One Equation and Point (2,0) or (X,Y)

Step 2 Plug in and solve

0=4-6+2
0=0
Done and Answer is Yes it does fit.
First we have to multiply the numerator and the denominator by 5:
