Question

Convert the following products into sum or difference If angles are
given in degrees, evaluate from tables 2 sin 48 degrees cos 12
degrees?

Anuradha Sharma · Accepted Answer

We have to evaluate 2sin48 degree cos 12 degree= sin48+12+sin48-12
Using formula 2sinacosb=sina+b+sina-b=sin60+sin36=32+0 5877
