Nettet8. apr. 2012 · 1 The main obstacle here is the square root. It is likely that eliminating it will allow us to proceed. So we want something squared minus 1 is the square of something. That leaves secant (or cosecant) as the best option. As N3buchadnezzar states, it is not the only option. Consider the formulas $ (m+n)^2=m^2+2mn+n^2, (m-n)^2=m^2 … NettetYou should be familiar with the standard integrals \\displaystyle\\int \\dfrac{1}{a^2 + x^2} \\dx = \\dfrac{1}{a} \\tan^{-1} \\left( \\dfrac{x}{a} \\right) + c ... contract of support
