Can you please help me solve this e^(2x+4) = 3

2x + 4 = ln(3) x = ½ln(3) - 2 = ln(√3) - 2-Take Ln (2x+4) = Ln (3) 2x = Ln(3) - 4 x= 0.5 Ln(3) -2 Use calculator-ln each side 2x+4=ln(3) 2x=ln3-4 x=(ln3-4)/2

How to integrate cot^4(x)

Note that: ∫ cot^4(x) dx = ∫ [cot^2(x) * cot^2(x)] dx = ∫ cot^2(x)[csc^2(x) - 1] dx = ∫ [cot^2(x)csc^2(x) - cot^2(x)] dx = ∫ cot^2(x)csc^2(x) dx - ∫ cot^2(x) dx. The first integral can be integrated
