These identities are used to reduce integrals so that they can be solved, as well as to find the values for angles that are not specifies on the unit circle. How do you find half-angle identity? A half-angle trig identity is found by using the basic trig ratios to derive the sum and...
Identities are important for fulfilling numerous objectives, such as the simplification of expressions, completion of incomplete identities, etc. Sometimes, we apply appropriate identities to prove an unidentified identity. Some identities are given below. ...

To find the derivatives of inverse trigonometric functions, we use implicit differentiation. For example, to find the derivative of sin-1x, we assume that y = sin-1x from which we get sin y = x. Differentiating both sides with respect to x, we get cos y dy/dx = 1. From this, dy...

that make the equation true. For example, the equation sin x + 1 = cos x has the solution x = 0 degrees because sin x = 0 and cos x = 1. Use trig identities to rewrite the equation so that there's only one trig operator, then solve for the variable using inverse trig operators...
