prove-3(0)cos(3t)+3(1)sin(3t)=3sin(3t)

prove

- 3 (0) cos (3 t) + 3 (1) sin (3 t) = 3 sin (3 t)

True

Solution steps

- 3 \cdot 0 \cdot cos (3 t) + 3 \cdot 1 \cdot sin (3 t) = 3 sin (3 t)

Manipulating left side

- 30 cos (3 t) + 31 sin (3 t)

Simplify

= 3 sin (3 t)

We showed that the two sides could take the same form

\Rightarrow True

(1 + cos (x)) (1 - cos (- x)) = sin^{2} (x)

cot^{2} (x) = csc^{2} (- 1)

1 + sin (2 θ) = (sin (θ) + cos (θ)) 2

tan^{2} (x) - tan (x) + 1 = sec^{2} (x) - tan (x)

\frac{1 - sin ( a )}{1 + sin ( a )} = \frac{cos ( a )}{1 + sin ( a )}
