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) ... If (1+√1+x)tanx=1+√1−x, then sin 4x is equal to · The correct Answer is:C · We have, tanx=1+√1−x1+√1+x ⇒tanx=1+√1−sinθ1+√1+sinθ,wherex=sinθ ⇒tanx=1+cosθ2−sinθ21 ... Prove that 1/(tanx) + tanx = 1/sinxcosx. The key here is to realise that tanx = sinx/cosx. If we write out ... tanx = sinx cosx secx = 1 cosx cosecx = 1 sinx cotx = 1 tanx. Fundamental trig identity. (cosx). 2. + (sinx). 2. = 1. 1 + (tanx). 2. = (secx). 2. (cotx). 2. + 1 ... Given: secx + tanx = 3 Concept Used: If secx + tanx = y. then secx - tanx = 1/y cosec2x - cot2x = 1 tanx = 1/cotx.
