Hello there, this is a question from my Calculus Methods class of Software Eng subject. I need a step by step solution with the written method in the question, otherwise I'll get 0 sadly.

Thanks in advance:)

Localize all the roots of the equation: 2x2cos25x0.5x2cos25x19sin(2x+9)=sin25x+0.5x2sin25x4 Calculate of one of the localized roots by the method of simple iterations ith accuracy 102 (perform 3 iterations)
