This identity shows how sine and cosine are cofunctions—they “complement” each other when angles add up to 90°. On the other hand, cos(π/2 + θ) is equal to −sin(θ). This identity introduces a sign change, which happens because adding to π/2 moves the angle into a different quadrant where cosine is negative. Together, thes

mathswithmuza on Instagram: "The identity cos(π/2 − θ) = sin(θ) is a fundamental result in trigonometry that highlights the close relationship between the sine and cosine functions. This identity comes from the idea of co-functions, where the sine of an angle is equal to the cosine of its complement. In a right triangle, if one of the acute angles is θ, then the other acute angle is π/2 − θ (or 90° − θ in degrees), since the angles in a triangle must add up to 180°. The sides opposite these angl
