Given a value of sin Ө, cos Ө or tan Ө, we can find the value of the angle Ө using the sin-1, cos-1 or tan-1 keys, respectively. On most calculators, sin-1, cos-1 and tan-1 is obtained by first pressing . INV. or . 2nd F. and then pressing sin, cos or tan, respectively. Example. Find the value of Ө, to the nearest minute, given that: (i ...

Note : Equations of the type a cos ( + b sin ( = c where a, b and c are constants, to solve it, we first express a cos ( + b sin ( = R cos (( ( () where R > 0 and ( is acute. Example 7.10 Find the general solution of the equation cos x + cos 2x + cos 3x = 0 and hence deduce the values of x between - ( and (.
