prove-5cos(0)-8.6602500000000…sin(0)=-5

prove

- 5 cos (0) - 8.6602500000000 \dots sin (0) = - 5

True

Solution steps

- 5 cos (0) - 8.66025 \dots sin (0) = - 5

Manipulating left side

- 5 cos (0) - 8.66025 \dots sin (0)

Simplify

- 5 cos (0) - 8.66025 \dots sin (0) : - 5

= - 5

We showed that the two sides could take the same form

\Rightarrow True

0 sin (\frac{π}{2}) + 1 = cos (2 π)

sin (x) = tan (x) \cdot cos (x)

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

\frac{1 + cos ( 2 x )}{2 sin ^{2} ( x )} = cot^{2} (x)

sec (θ - π) = - sec (θ)
