In the paper, the authors find series expansions and identities for positive integer powers of inverse (hyperbolic) sine and tangent, for composite of incomplete gamma function with inverse hyperbolic ...

This function is used for input variable screening. It is shown above in its only two active variables. A small error term ε ~ N(0, 0.05 2) is added to the response ...

Solve the equation \(4\sin x^\circ - 3 = 0\), where \(0 \le x \textless 360\). From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(0^\circ\) and ...

Many students think they've solved a trig equation when they get one answer (one size of angle \(x^\circ\)). However there's often more than one answer expected so be aware of this. Let's remind ...
