Given: secx + tanx = 3 Concept Used: If secx + tanx = y. then secx - tanx = 1/y cosec2x - cot2x = 1 tanx = 1/cotx. May 23, 2016 ... 1 Answer ... x=nπ+π4 , where n is an integer. Explanation: tanx=1 , but as tan(π4) ... Some trigonometric identities are tan ⁡ x = sin ⁡ x cos ⁡ x , sin 2 x + cos 2 x = 1 , cos ⁡ 2 x = cos 2 x − sin 2 x. 1 + x2. 5. Page 6. d. f(x) = xarctanx. (Note that the inverse tangent function arctanx is often written tan-1 x, but it does not equal (tanx)-1.) e. f(x) ...

Since tanx = sinx/cosx, anywhere on the unit circle where sinx = cosx is where tanx = 1 which is where x = π/4 or x = 5π/4. Sep 16, 2020 ... sec x - tanx = (1/cosx) - (sinx/cosx) = (1-sinx)/cosx secx+tanx = (1+sinx)/cosx the product of the two is (1-sinx)( 0. * tanx is not defined at 90◦ or 270◦. 2. Find all the solutions to sinx = 1. 2 with 0 ⩽ x < 360◦. • ... cos2 = 1 in one of the equivalent forms sin2 x = 1−cos2 x , cos2 x = 1 ... 1) dx = tanx − x + C. To do higher powers of tanx, you separate tan2 x and ...
