Question

is it correct to Say that sino = cos(90-0)?
why?​

Answer 1

Step-by-step explanation:

Yes, this is correct because sinФ and cosФ are complimentary angles.

For example, if sinФ = sin0 and cosФ = cos0, then sinФ + cosФ = 90°.

This is because sin0 = 0° and cos0 = 90°.

So, since sin0 + cos0 = 90, sin0 = cos(90-0) and vice-versa i.e.,

cos0 = sin(90-0).
