From the table below, you can notice that sech is not supported, but you can still enter it using the identity `sech(x)=1/cosh(x)`. If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and … Feb 19, 2010 Using the formula cos (3 x) = 4 cos 3 (x) − 3 cos (x) is actually quite useful, but first we have to do x = 2 y, then we get 8 y 3 − 6 x + 1 = 0 Now we have the 4:-3 ratio and we can sub in y = cos (θ) Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.

## If sin A = 3/5 then find the value of sin 3A. Solution : In this problem we have given the value of Sin A. Now we need to find the value of sin 3A. To solve this problem we have a formula for sin 3A.In this formula we have to plug 3/5 instead of the term sin A. Sin 3A = 3 Sin A - 4 sin ³ A. sin 3A = 3 (3/5) - 4 (3/5)³
