aum · Answer

sin(x) = sin(x) / cos(x) * cos(x) = tan(x) * cos(x) = tan(x) / sec(x)

micahm · Answer

The Pythagorean trigonometric identity is a trigonometric identity expressing ... Values of 0 and π/2 are trivially proven by direct evaluation of sin and cos at those angles. ... By the periodicity identities we can say if the formula is true for −π < θ ≤ π ... The following table shows how this is done by dividing each element

Everything you posted showed up as question marks :o @micahm which one is it..

micahm · Answer

A or B is what i had in mind

aum · Answer

In my previous reply I showed sin(x) = tan(x) / sec(x).
Therefore, sin(0) = tan(0) / sec(0)
