Question 817271
<ul><li>What are you/we supposed to do with this? Please include the instructions for the problem, not just the equation/expression.</li><li>What is "tg"??<ul><li>Is it supposed to be "tan" (since you did post this in the Trigonometry category)? If yes, then there is no multiplication between the function name and its argument. For example: tan(3x-2) not tan*(3x-2).</li><li>Or is "tg" something else? If so then more information will be needed to solve the problem.</li></ul></li></ul>Please re-post your question.
