Ive been given very little notes from my teahcer, and cant do these. looked online, but its was no use. 1. Using the identities to find the vales of each expression (no calc.) (i) sin t = 15/17 , cos t = 8/17 find remaining trig functions (ii) sec^2 Pie/12 - tan^2 Pie/12 2. Find exact value (i) tan* = -3 , cos *>0 3.Use reference angles to find exact value (no calc.) (i) cos 225* (ii) sin ( -pie/6 ) Thanks a bunch!
