how to tan^2

[mdewolff-2]

Hello,

I want to calculate dynamic deflection of the worm in a worm drive. The formula given in my book does not seem to work in Mathcad Prime 3.0.

In the book there is no multiplier (*) printed after tan^2 and cos^2. There is just empty space. I did change the formula around in all kinds of ways.

I put tan inside parenthesis like (tan)^2, or (tan^2*(gamma+Q)), or (tan(gamma+Q)^2) but nothing works.

What do I do wrong?

Thanks maurits

tan²(x) = tan(x)²

You have to use the second format in Mathcad.

Thanks! That worked.

If you would like to match the notation in your book you could first define

and then use this newly defined function

Note that the first exponent 2 in the function definition is not an exponentiation sign type by ^2 but rather the small superscript available from the keyboard (on mine via altgr+2).
