In 31-42, rotate the axes so that the new equation contains no xy-term. Analyze and graph the new equation. Refer to 21-30 for 31-40. 16x2 + 24xy + 9i - 60x + SOy = 0

1/3 Trigonometric Functions functions that utilize trigonometric values… I.e. cos, sin, and tan. To find the values of trigonometric functions just remember the acronym S.O.H.C.A.H.T.O.A. S.O.H.C.A.H.T.O.A helps people remember how to find the values for sin, cos, tan. Keep in mind this is for finding values in right triangles. o SOH Sin= opposite/hypotenuse. o CAH Cos= adjacent/hypotenuse. o TOA Tan= opposite/adjacent or sin/cos Opposite and adjacent are referring to sides opposite or adjacent to the angle the trigonometric function is trying to define. Several other trig functions can be found usinig the three main trig functions. Csc 1/sin Sec 1/cos Cot 1/tan or
