Calculator wich uses trigonometric formula to simplify trigonometric expression.
This calculator allows through various trigonometric formula to calculate trigonometric expression. Trignometric expressions are expressions that involve sine functions, cosine functions , tangent function ...
To simplify trigonometric expressions, the calculator uses various formulas of trigonometry, here are some examples of formulas trigonometric used by the calculator:
`AA x in RR, k in ZZ`,
This is only a small example of the many trigonometric formulas used by this trigonometric calculator.
When the calculator simplifies a trigonometric expression, it indicate the formulas used to arrive at the result, in the section reserved for the detail of the calculations.
To simplify a trigonometric expression, enter the expression to simplify and apply the simplify_trig function. Thus, for the simplification of the following expression `cos(x+pi)+2*sin(x)`, enter simplify_trig(`cos(x+pi)+2*sin(x)`) , after calculation the simplified form of the trigonometric expression is returned.
This other example shows how to calculate the trigonometric expression `cos(pi-x)`: simplify_trig(`cos(pi-x)`) .
The trigonometric calculator can simplify alphanumeric expressions but also purely numerical expressions.
simplify_trig(expression), where expression represents the trigonometric expression to be simplified.
simplify_trig(`cos(x+pi)`) returns `-cos(x)`
