Dear Tasneem, try using the internal built-in functions TrigReduce (for simplyfing trigonometric expression) or TrigToExp (for transforming trig expression in exponential form, perhaps more manageable).

Sir ,

You can use matlab programs to solve this.

exp

funm(A, @exp)

log

funm(A, @log)

sin

funm(A, @sin)

cos

funm(A, @cos)

sinh

funm(A, @sinh)

cosh

funm(A, @cosh)

these are some examples. for more information you can visit https://in.mathworks.com/help/matlab/ref/funm.html
