You don't need to type any spaces as you enter the functions. Scientific Notebook interprets the trigonometric functions and formats the expression correctly, displaying the function names in gray.

  1. ClickitbpF20.125pt20.125pt2pttext.wmfor, from the Insert menu, choose Math to start mathematics.

  2. Type sinxcosy. Your screen shows the expression sin x cos y.

  3. Type +cosxsiny. On your screen, you see sin x cos y + cos x sin y

  4. From the Maple menu, choose Combine and then choose Trig Functions.

    Your result is: sin x cos y + cos x sin y = sin$\left(\vphantom{ x+y}\right.$x + y$\left.\vphantom{ x+y}\right)$.
