t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are.

cos(x + π 2) = cosx ⋅ cos( π 2) − sinx ⋅ sin( π 2) = cosx ⋅ 0 −sinx ⋅ 1 = − sinx. Finally. cos(x + π 2) = − sinx. Answer link. Use the known trigonometric identity cos (a+b)=cosa*cosb-sina*sinb we have that cos (x+pi/2)=cosx*cos (pi/2)-sinx*sin (pi/2)=cosx*0-sinx*1=-sinx Finally cos (x+pi/2)=-sinx.

If you have this identity, it's straight forward to show formally: $\cos(a + b) = \cos a \cos b - \sin a \sin b$. But I think an intuitive approach going back to the unit circle is more instructive. $\endgroup$

Convert from 1 cos(π 2 + x) to sec(π 2 + x). Divide 0 by 1. Multiply 0 by sec(π 2 + x). Subtract 1 from both sides of the equation. Divide each term in - tan(π 2 + x) = - 1 by - 1 and simplify. Tap for more steps. Take the inverse tangent of both sides of the equation to extract x from inside the tangent.
