**EQUATION SOLVER**

The calculator will endeavor to locate the roots (exact and complex numerical, real and), i.e. solve for x, y , or any other variable in any equation (linear quadratic, polynomial or rational) as well as irrational, exponential trigonometric, logarithmic hyperbolic absolute value) in the interval you specify.

Your input: Solve this equation (x2-3x-2)sin(x)=0 for the variable x. (-,)

ANSWER

x=32+17–23.56155281280883

x=32-17–2-0.56155281280883

xnZ

Make use of a calculator for solving the equation based on the range 0= 2p th. Round the answers up to 2 decimal points.

#### How do you locate all the solutions within the range [0,2p) without the use of an calculator

3sinx=2cos2x?

Solve 3sin x = 2cos^2 x
