Evaluate trig functions using identities

The video tutorial explains the properties of sine as an odd function and cosine as an even function. It covers the identities of sine and cosecant, demonstrating how to calculate the sine of a negative angle and the cosecant using reciprocal identities. The tutorial concludes with a calculation example, showing how to combine these identities to find a solution using a calculator.
