May 8, 2018 ∫ dx 1 + secx = x − tan( x 2) + c explanation: The strategy is not obvious.multiply and divide by (sec x + tan x); Thus, we have ∫( secx(secx +tanx) secx +tanx)dx ∫ sec2x + secxtanx secx + tanx dx now, make the following substitution: All common integration techniques and even special functions are supported. Web question 2 (5 points) use integration by parts with u = sec x, dv = sec2 x dx to solve the integral z sec3 x dx. Web ∫secx−1dx is equal to medium solution verified by toppr i=∫( secx−1)dx i=∫ cosx1 −1=∫ cosx1−cosxdx 1−cos2x=2sin 2(x) cos2x=2cos 2x−1 i=∫ 2cos 2(x/2)−12sin 2(x/2) dx u=cosx/2du=−sin(x/2)× 21dx i=∫ 2u 2−12×(sin 2(x/2))× 2−1×sin(x/2)du i=−2 2∫ 2u 2−11 du i= 2−2 2∫ u 2− 211 du i=∫ x 2−a 2dx =log∣x+ x 2−a 2∣+c i=−2log∣u+ u 2−1/2∣+c The function value is the height and dx is the. Cosx = 1 − tan2(x 2) 1 + tan2(x 2) 1 1 + secx = 1 1 + 1+tan2( x 2). [2] he applied his result to a problem concerning nautical tables.
• the identity tan2 x + 1 = sec2 x might be helpful. 1 1 + secx = 1 1 + 1 cosx use now the parametric formula: It helps you practice by showing you the full working (step by step integration). Cosx = 1 − tan2(x 2) 1 + tan2(x 2) 1 1 + secx = 1 1 + 1+tan2( x 2). Our calculator allows you to check your solutions to calculus exercises. All common integration techniques and even special functions are supported. Let u = sec(x) u = sec ( x). (secx)′ = secxtanx (secx)′′ = 2sec3x − secx then ∫sec3xdx = 1 2∫secxdx + 1 2∫(secx)′′dx = 1 2ln|secx + tanx| + 1 2(secx)′ + c = 1 2ln|secx + tanx| + 1 2secxtanx + c. U = secx +tanx du = (secxtanx +sec2x)dx = (sec2x + secxtanx)dx ∫ 1 sec(x) tan(x) dx ∫ 1 sec ( x) tan ( x) d x.
