∫ tan(x) dx =

∫ sin(x)/cos(x) dx

Let cos(x) = u

Therefore, sin(x) = -du/dx >>>> (Derivative of cos(x))

∫ (-du/dx)/u dx >>>>>>>>>>> Substitute the values

∫ -du/udx dx

∫ -du/u >>>>>>>>>>>>>>>>> dx * 1/dx cancel each other out

∫ -1/u du

= -ln(u) + C

= -ln(cos(x)) + C >>>>>>>>>>> Substitute cos(x) back into u

Integration of tan pow4x?

integral of (tanx)^4 (tanx)^4 = (tanx)^2 (tanx)^2 =(sec^2 x - 1)(tan^2 x) =(sec^2 x)(tan^2 x) - tan^2 x = integral of sec^2 x tan^2 x dx - integral of tan^2 x dx First, integral of sec^2 x tan^2 x dx Let u = tanx because that would make du = sec^2 x dx so then we have integral of u^2 du which is (1/3)u^3 substituting back in tanx we get (1/3)tan^3 x Next, integral of tan^2 x tan^2 x = sec^2 x -1 integral of sec^2 x - 1 = integral of sec^2 x dx - integral 1 dx = tanx - x so putting it all together we have integral of tan^4 x dx = (1/3)tan^3 x - tanx + x + C

Tan plus cot divided by tan equals csc squared?

(tanx+cotx)/tanx=(tanx/tanx) + (cotx/tanx) = 1 + (cosx/sinx)/(sinx/cosx)=1 + cos2x/sin2x = 1+cot2x= csc2x This is a pythagorean identity.
