number Required The angle in radians for which we want to calculate the cosecant. Return Parameter: The cosecant of an angle is specified in radians. Use of CSC Function: 10. The CSCH Function Function Objective: The CSCH function is applied to return the hyperbolic cosecant of an angle...
The limits involving trig functions have two cases according to the dummy variation: near 0 or near ∞. The answers and the techniques used in these two cases have almost nothing in common. But it’s important to note that we can’t tell what case we’re dealing with just by looking at...
For example, some trigonometric identities or formulas that are helpful when dealing with finding trigonometric functions of large angles are as follows: $$\begin{align*} \sin \left( {360 + \theta } \right) &= \sin \left( \theta \right)\\ \cos \left( {360 + \theta } \right) &=...
