Does anyone know of websites where I can find many problems on the topic in the title line (my textbook has far too few)?
Thanks!

The basic trigonometric identities are sine, cosine, tangent, cotangent, secant, and cosecant. These functions relate the sides and angles of a right triangle and can also be expressed as ratios of the sides.
Trigonometric identities can be used to simplify equations and expressions involving trigonometric functions. By substituting in the identities, the equations can be reduced to simpler forms that are easier to solve.
The Pythagorean identity, also known as the Pythagorean theorem, states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In terms of trigonometric functions, this can be expressed as sin^2(x) + cos^2(x) = 1.
Trigonometric identities can be used to prove other identities by substituting in known identities and manipulating the equations to show that they are equal. This is often done using algebraic techniques and the properties of trigonometric functions.
Some common mistakes to avoid when working with trigonometric identities include: not properly simplifying expressions, not using parentheses when necessary, and forgetting to consider the restrictions on certain trigonometric functions (such as division by zero or undefined values).
