A summary of trigonometric function deformation formulas
To learn mathematics well, we must master the formula of trigonometric function. The following summarizes the deformation formula of mathematical trigonometric function, hoping to help you learn mathematics.

Trigonometric function deformation formula sin(π/2+α)=cosα.

cos(π/2+α)=-sinα

tan(π/2+α)=-cotα

cot(π/2+α)=-tanα

sin(π/2-α)=cosα

cos(π/2-α)=sinα

tan(π/2-α)=cotα

cot(π/2-α)=tanα

sin(3π/2+α)=-cosα

cos(3π/2+α)=sinα

tan(3π/2+α)=-cotα

cot(3π/2+α)=-tanα

sin(3π/2-α)=-cosα

cos(3π/2-α)=-sinα

tan(3π/2-α)=cotα

cot(3π/2-α)=tanα

The trigonometric function value of special angle remembers the formula of 30, 45 and 60 degrees, and the trigonometric function remembers it firmly;

The denominator chord bisector is three, and the numerator should add a root sign;

One, two, three, three, two, one, three, nine, twenty-seven;

Tangent and sine increase, cosine function decreases.
