tan(x) = sin(x)/cos(x)
Therefore, all trigonometric ratios can be expressed in terms of sin and cos. So the identity can be rewritten in terms of sin and cos.
Then there are only two "tools":
sin^2(x) + cos^2(x) = 1
and sin(x) = cos(pi/2 - x)
Suitable use of these will enable you to prove the identity.

How do you solve identities on trigonometry?
Unlike equations (or inequalities), identities are always true. It is, therefore, not possible to solve them to obtain values of the variable(s).
What are the identities in trigonometry?
In trigonometry, identities are mathematical expressions that are true for all values of the variables involved. Some common trigonometric identities include the Pythagorean identities, the reciprocal identities, the quotient identities, and the double angle identities. These identities are used to simplify trigonometric expressions and solve trigonometric equations.
How do you find x in a trignometric functions?
find x. given is 14 and a 90 degree angle
Where can one find a list of trigonometric identities?
Trigonometric identities involve certain functions of one or more angles. These identities are useful whenever expressions involving trigonometric functions need to be simplified.
Can you square the trigonometric reciprocal identities if you need to for example sine squared equals 1 divided by cosecant squared?
Yes, this is a perfectly legitimate thing to do in the trigonometric functions. I will solve all your math problems. Check my profile for more info.
