Verify the Identity sec(x)-tan(x)sin(x)=cos(x) Start on the left side. Because the two sides have been shown to be equivalent, the equation is an identity.

Because the two sides have been shown to be equivalent, the equation is an identity. Type your expression into the box to the right. Your expression may contain sin, cos, tan, sec, etc. When you click the button, this page will try to apply 25 different trig. identities that it knows about to simplify your expression.

It is convenient to have a summary of them for reference. These identities mostly refer to one angle denoted θ, but there are some that involve two angles, and for those, the two angles are denoted α and β.
