EML 5060Analysis in Mechanical Engineering Fall 2013
Test 1 Van Dommelen (http://www.eng.famu.fsu.edu/~dommelen) Due W 09/04/13

Hand in the solution to this test on the date stated above (5% of your final grade). Read carefully. And look it up. Answer questions in order from left to right, top to bottom. You must work alone. You probably want to consult a math handbook.

Neatly draw the graph of the following functions, showing the locations of 0 and $\pm 1$ on each axis. Give the derivative. Indicate non-principal values as a broken line. Make sure that you give enough of the curves to clearly demonstrate all features. Make sure that you have answered all parts, including derivatives.

$$1) \quad 2x-2 \qquad \qquad \qquad \qquad 2) \quad x^2 + 1 \qquad \qquad \qquad \qquad 3) \quad x^4 - x^2$$

$$4) \quad \sin(x)\qquad \qquad \qquad \qquad 5) \quad \arcsin(x)\qquad \qquad \qquad \qquad 6) \quad \sinh(x)$$

$$7) \quad \cos(x)\qquad \qquad \qquad \qquad 8) \quad \arccos(x)\qquad \qquad \qquad \qquad 9) \quad \cosh(x)$$

$$10) \quad \tan(x)\qquad \qquad \qquad \qquad 11) \quad \arctan(x)\qquad \qquad \qquad \qquad 12) \quad \tanh(x)$$

$$13) \quad \ln(x)\qquad \qquad \qquad \qquad 14) \quad e^x\qquad \qquad \qquad \qquad 15) \quad \tan(x^2)$$

Find (include any integration constants and absolute signs):
