Hello Student,
Please find answer to your question below

I = \int (3sinx-4cosx+\frac{5}{cos^{2}x}-\frac{6}{sin^{2}x}+tan^{2}x-cot^{2}x)dx
I = \int (3sinx-4cosx+5sec^{2}x-6cosec^{2}x+tan^{2}x-cot^{2}x)dx
I = \int (3sinx-4cosx+5sec^{2}x-6cosec^{2}x+sec^{2}x-1-cosec^{2}x+1)dxI = \int (3sinx-4cosx+6sec^{2}x-7cosec^{2}x)dx
I = -3cosx-4sinx+6tanx+7cotx+c
