Evaluate: `int(secx)/(sec2x)dx`

Text Solution

Verified by Experts

We have given,
`int(secx)/(sec2x)dx`
As we know, `sec x=1 / cos x, sec 2 x=1 / cos (2 x)`
So, the above equation becomes,
`implies frac{frac{1}{cos x}}{frac{1}{cos 2 x}} `
`=frac{cos 2 x}{cos x}`
Hence the equation now becomes
`implies int frac{cos 2 x}{cos x} d x`
