The definite integral of from to , denoted , is defined to be the signed area between and the axis, from to Both types of integrals are tied together by the fundamental theorem of calculus This states that if is continuous on and is its continuous indefinite integral, then This means Sometimes an approximation to a definite integral isTo integrate 2sec^2x tanx, also written as ∫2sec 2 x tanx dx, 2 sec squared x tan x, and 2(sec x)^2 tanx, we start by recognising that the differential of one half is within the other half of the same expression In this case, the differential of tanx is sec squared x, which should fill you with great confidence to use the u substitution methodSolve the integral = ln u C substitute back u=cos x = ln cos x C QED 2 Alternate Form of Result tan x dx = ln cos x C = ln (cos x)1 C = ln sec x C

The textbook I was reading seemed to be asking me to integrate $\sec^2 x$ without having introduced the standard trig integrals $\endgroup$ – hertzsprung Sep 22 '13 at 2 We do need to know that $1 \tan^2 t = \sec^2 t = 1/\cos^2 t$ Then $\cos^2(x/2) = 1/(1\tan^2(x/2)) = 1/(1u^2)$, so from the doubleangle formulas for sine andIt is not true that tan x = sec2 x However, you can see from the graph in Figure 1 that your two answers may only differ by aJun 05, 11 · The integral of the secant function was one of the "outstanding open problems of the midseventeenth century", solved in 1668 by James Gregory He applied his result to a problem concerning nautical tables In 1599, Edward Wright evaluated the integral by numerical methods – what today we would call Riemann sums
