The variablet is a real number and P= is the point on the unit circle that corresponds to t. Find the exact values of the six trigonometric functions of t.

(Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)

Add, subtract, multiply, or divide as indicated. list any restrictions for the variable(s) and simplify the answers when possible. 1) x-2 / x+5 + 3x / 2x-1 2) x+6 / x-6 - x^2 / x+6 3) x+9 / x-4 + x+2 / x^2-11x+28 4) x / x^2-64 + 11 / 2x^2+11x-40 5) 5 / x + 11 / x-3 - x-4 / x^2+2x-15
