Question
A series is given with one term missing. Choose the
correct alternative from the given ones that will complete the series. P24Â Â Â R35Â Â Â T48Â Â Â ? Â Â Â X80Solution
Logic: In this series, the letters progress by: +2 For numbers 52 - 1 = 24, 62 - 1 = 35 and so on therefore the next series will be V63 .
Find the value of tan(75°) using the identity for tan(A+B).
If cos2B = sin(1.5B + 20o), then find the measure of 'B'.

If √3cosec 2x = 2, then the value of x:
if 8 sin 2 x + 3 cos 2 x = 4  then find tan x
If cos 2A = 17, then find cos A
