In c math sqrt is a math class method which is used to calculate the square root of the specified number. Evaluate trigonometric identities with a given angle.

We recorded our thinking using this build it draw it write it bdw document. Use the create nrows ncols type method or the similar mat nrows ncols type fillvalue constructor. The following example uses sin to evaluate certain trigonometric identities for selected angles. To create a rectangle you have to pass the four parameters in this function.

Number whose square root is to be calculated and type of this parameter is system double. Creates a text string to draw.
