(1+tanx)^2+(1+cotx)^2 |
|
Answer» = 1-2tanx+tan^2x+1-2cotx+cot^2x = (1+tan^2x)+(1+cot^2x)-2(tanx+cotx)
We KNOW that; 1+tan^2x = sec^2x 1+cot^2x = cosec^2x sin^2x+cos^2x = 1 (tanx+cotx) = sinx/cosx+cosx/sinx = (sin^2x+cos^2x)/(SINXCOSX) = 1/(sinxcosx) = secxcosecx
(1-tanx )^2 + (1-cotx )^2 = (1+tan^2x)+(1+cot^2x)-2(tanx+cotx) = sec^2x-2secxcosecx+cosec^2x
(secx-cosecx)^2 = sec^2x-2secxcosecx+cosec^2x
(1-tanx )^2 + (1-cotx )^2 = (1+tan^2x)+(1+cot^2x)-2(tanx+cotx) = sec^2x-2secxcosecx+cosec^2x = (secx-cosecx)^2
