I would like MATLAB to perform trigonometric simplification such as 1-cos(x)^2 = sin(x)^2, when x is a symbolic expression. Currently, it returns 1-cos(x)^2. Reproduction Steps: syms a b ...Equation to solve, specified as a symbolic expression or symbolic equation. The relation operator == defines symbolic equations. If eqn is a symbolic expression (without the right side), the solver assumes that the right side is 0, and solves the equation eqn == 0.The "Simplify" operation in MATLAB is a built-in function that simplifies mathematical expressions. It is particularly useful for streamlining symbolic derivatives, where it can combine and simplify terms, factor polynomials, and perform other operations to simplify the resulting expression. 2.Try combining log(a) + log(b). Because a and b are assumed to be complex numbers by default, the rule does not hold and combine does not combine the terms. syms a b. S = log(a) + log(b); combine(S,'log') ans =. log(a) + log(b) Apply the rule by setting assumptions such that a and b satisfy the conditions for the rule.
