Verify that the equation is an identity. sin x cOS X secx + = sec?x-tan? CSC X Both sides of this identity look similarly complex. To verify the identity, start with the left side and simplify it. Then work with the right side and try to simplify it to the same result. Choose the correct transformations and transform the expression at each step COS X sin x secx CSC X The left-hand side is simplified enough now, so start working...

SWI. U 7. Consider the right triangle AABC with the right angle 2C = 90° and sides c = 10 cm, a = 8 cm, b = 6 cm. If angle LA is opposite to side a, find sin A,cos A, tan A, cot A, sec A, CSC A.
Establish the identity. sec - csc = sin e- cos e sec csc Write the left side as a difference of two quotients. sec csc sec @csc @ Cancel the common factors from the previous step. Do not apply any trigonometric identity. 1-0 The expression from the previous step then simplifies to sin 0 - cos using what? O A. Even-Odd Identity O c. Quotient Identity O E. Pythagorean Identity
