if cosa+sina=√2cosa then prove cosa-sina=√sina
if you were to find the cos75°, which formulas could you use? Would you get the same answer using both methods? How would you know? please explain
what are the solutions to cos (30) = -1 in the interval (0,2radian). Please I need step by step instructions on how the answer was found. P.S also looking for a...
FIND THE VALUE OF COS TETA
Simplify. Please i need help! p- stands for Pi (radians). and yeah, its like this (a.cosx - b.sinx) / (b.cosx + a.sinx). Amd Tan^(-1) stands for the tangent inverse (tan inverse). We need...
