The equation sin x = cos x can also be solved by dividing through by cos x. If we put k = 0 and k = 1 we get the solutions /4 (45°) and /4 + = 5 /4 (45°+ 180°= 225°). To solve the inequality sin x > cos x we need to see which is the greater sin x or cos x on the intervals between the solutions /4 and 5 /4.

given that Sin inverse X + Sin inverse Y is equal to 3 pi by 2 and hence we know that Sin inverse X is equal to pi by 2 minus Cos inverse X and similarly Sin inverse Y is equal to pi by 2 minus Cos inverse y. Now we're adding Sin inverse X + Sin inverse y h pi by 2 minus Cos inverse X + 5 by 2 minus Cos inverse Y is equal to 3 pi by 2 and then it makes Pi minus Cos inverse X + Cos inverse Y is equal to 3 pi by 2 and then we get pi -3pi by 2 is equal to Cos inverse X + Cos inverse Y. So Answer becomes minus pi by 2.

A×A={ (1,3,5)×(1,3,5)} ={(1,1)(1,3)(1,5)(3,1)(3,3)(3,5)(5,1)(5,3)(5,5)} R1={(1,3)(3,1)(1,1)(3,3)} R2= {(1,3)(3,1)(1,1)(3,3)(1,5)(3,5)(5,5)} (note: 1 is related to 5, 3 is related to 5 so 5 is related to 5)
