can u show me the solution for getting the inverse of cschx

Solution

The inverse of the hyperbolic cosecant function, csch(x)\text{csch}(x), can be derived using the following process:

Step-by-Step Solution for Finding the Inverse of csch(x)\text{csch}(x)

We start with the equation:

y=csch(x)y = \text{csch}(x)

The hyperbolic cosecant is defined as:

y=1sinh(x)y = \frac{1}{\sinh(x)}

Now, solve for xx in terms of yy:

y=1sinh(x)    sinh(x)=1yy = \frac{1}{\sinh(x)} \implies \sinh(x) = \frac{1}{y}

Next, recall that the inverse of sinh(x)\sinh(x) is arsinh(x)\text{arsinh}(x), which is expressed as:

x=arsinh(1y)x = \text{arsinh}\left(\frac{1}{y}\right)

The formula for the inverse hyperbolic sine (arsinh) is:

arsinh(x)=ln(x+x2+1)\text{arsinh}(x) = \ln(x + \sqrt{x^2 + 1})

So, we substitute 1y\frac{1}{y} into the inverse hyperbolic sine formula:

x=ln(1y+(1y)2+1)x = \ln\left(\frac{1}{y} + \sqrt{\left(\frac{1}{y}\right)^2 + 1}\right)

Simplify the expression:

x=ln(1y+1y2+1)x = \ln\left(\frac{1}{y} + \sqrt{\frac{1}{y^2} + 1}\right)

x=ln(1y+1+y2y)x = \ln\left(\frac{1}{y} + \frac{\sqrt{1 + y^2}}{|y|}\right)

This gives the inverse of the hyperbolic cosecant function:

csch1(y)=ln(1y+1+y2y)\text{csch}^{-1}(y) = \ln\left(\frac{1}{y} + \frac{\sqrt{1 + y^2}}{|y|}\right)

Thus, the inverse of csch(x)\text{csch}(x) is:

csch1(x)=ln(1x+1+x2x)\boxed{\text{csch}^{-1}(x) = \ln\left(\frac{1}{x} + \frac{\sqrt{1 + x^2}}{|x|}\right)}

Let me know if you'd like further details!
