No explanations needed, only the correct solution, thank you:

Match the trigonometric expression with its simplified form. cot2(x) - csc2(x) O csc(x) O - 1 O sin(x) tan(x) O sec (x) O sec(x) O1Find the period and amplitude. y = -5 sin 5 period amplitudeEvaluate (if possible) the sine, cosine, and tangent at the real number t. (If an answer is undefined, enter UNDEFINED.) t = - 3 sin t = cos t= tan t=
