# find the exact value of cos 5pi/4

Prove that cos (sin-1 x) sqrt1 - x2 . find exact value in radians of the expression sin-1(1/2) please show all work!If an exact value cannot be given, give the value to the nearest ten-thousandth. sin[ cos-1(-sqrt3/2)]. what is the exact value of sin165 using sum and difference identities?can someone help me find the exact value ( trig question). I simplified to cos(7pi/12) but this not listed on the unit circle I have. the closest thing I have is 7pi/6 210degrees. so I know that its half that, at 105degrees (210/2). but I cant figure out how to find the exact value of it. How can I work out exact values for trig functions like sin(30) and cos(3pi/2 pre-calc Can someone help me find the exact value of 4csc(3pi/4)-cot(-pi/4)? Best Answer: depending on from which side you approach pi/2 it is positive or negative infinity. cos pi/12 cos 5pi/12 sin 5pi/12 sin pi/12.We all find plenty of tracks Find The Exact Value Of Sin 5pi 12 music mp3 although many of us simply display the tracks we consider will be the finest tracks.
