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...
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...
1.) Write sin 3x cos 5x as a sum of trigonometric functions. 2.) Write sin 2x - sin 3x as a product of trigonometric functions. Use the Sum and Difference Identities to find the exact value. sin (pi/12) The expression sec(θ) - cos (θ) can be written as the ...
