5.19 Using the series

sin (x) = x - x^{3} / 3! + x^{5} / 5! - x^{7} / 7! + ...

calculate the sine *x* to *n* terms. The GUI should consist of two **TextBox**es, three **Label**s and a button. One **TextBox** should allow the user to input the value of *x* in radians (2π radians in a circle). The second **TextBox** should allow the user to input the number of terms *n*. The larger the term, the more accurate the value. Display the results in a **Label**. The other two **Label**s should be used as prompts. The calculation should be performed and displayed when the button is pressed.
