Use a calculator to evaluate the expression. Round your result to two decimal places. $$ \arcsin 0.65 $$
Evaluate the expression without using a calculator. $$ \arctan (1) $$
An object weighing \(W\) pounds is suspended from the ceiling by a steel spring (see figure). The weight is pulled downward (positive direction) from its equilibrium position and released. The resulting motion of the weight is described by the function \(y=\frac{1}{2} e^{-t / 4} \cos 4 t, t>0,\) where \(y\) is the distance (in feet) and \(t\) is the time (in seconds). (a) Use a graphing utility to graph the function. (b) Describe the behavior of the displacement function for increasing values of time \(t\).
Use a graph to solve the equation on the interval \([-2 \pi, 2 \pi]\). $$ \cot x=1 $$
Use a graphing utility to graph the function and the damping factor of the function in the same viewing window. Describe the behavior of the function as \(x\) increases without bound. $$ h(x)=2^{-x^{2} / 4} \sin x $$
