1.

A and B are symmetric matricesmmetric matrix.valuate : j 8+x-x2dxvaluate: tan3 x dxnd the differential equation of al

Answer»

∫tan^3(x) dx from 0 to pi/4

∫tan(x)*tan²(x) dx from 0 to pi/4

∫tan(x)*(sec²(x)-1) dx from 0 to pi/4

=tan²(x)/2 + ln|cos(x)| evaluated from 0 to pi/4

=1/2 + ln(√2/2)
