`int (e^(x)(1+x))/(cos^(2)(xe^(x)))dx ` is

int(e^(x)(1+x))/(sin^(2)(xe^(x)))dx

int(e^(x)(1+x))/(cos^(2)(e^(x)x))dx equals

Evaluate int(2e^(x)(1+x)dx)/(cos^(2)(e^(x)x))

Ecaluate the following: (i) int(sec^(2)x)/(3+tanx)dx " (ii) " int(e^(x)-e^(-x))/(e^(x)+e^(-x))dx (iii) int(1-tanx)/(1+tanx)dx " (iv) " int(1)/(1+e^(-x))dx

int_(1)^(2)(1/(x)-(1)/(2x^(2)))e^(2x)dx

int(e^(tan^(-1)x))/(1+x^(2))dx

int(e^(x)+1)/(e^(x))dx :
