MATLAB: How to solve equation contains sin and cos

Question

Hello MATLAB experts,

I am seeking you assistance in solving an equation that has sin and cos. The equation and the commands and the resulted error are as follow

syms a b solve((350+1-((a*0.984807753012208)+(b*cosd(asind(((a*0.173648177666930))/b))))),b) ??? Error using ==> asind at 15 Argument should be real.

Thanks in advance, Aziz

Answer 1

The cosd function does not exist in the Symbolic Math Toolbox.

Try this:

syms a b
b_solved = solve((350+1-((a*0.984807753012208)+(b*cos(asin(((a*0.173648177666930))/b))))),b);
