18. If \( 2^{f(x)}=\frac{2+x}{2-x}, x \in(-2,2) \) and \( f(x)=\lambda f\left(\frac{8 x}{4+x^{2}}\right) \) then value of ' \( \lambda \) ' will be(1) 2(2) \( \frac{1}{2} \)(3) 1(4) -1

Answer»

2^f(x) = \(\frac{2+x}{2-x}\) ......(1)

f(x) = \(\lambda f(\frac{8x}{4+x^2})\)

f(1) = \(\lambda f(\frac{8}{5})\) ......(2)

2^f(1) = \(\frac31=3\) From (i)

⇒ f(1) = log₂3

2^{f(\(\frac85\))} = \(\frac{2+\frac85}{2-\frac85}\)

= \(\frac{18}2 =9\)

\(\therefore\) f(\(\frac85\)) = log₂9 = log₂3² = 2log₂³

46.	Find:\(\cfrac{sin(t - 2 \pi)}{sec(\frac{\pi}{2}-t)} \)
Answer» \(\cfrac{sin(t - 2 \pi)}{sec(\frac{\pi}{2}-t)} \) = \(\cfrac{sin(-(2\pi-t))}{cosect}\) (∵ sec (π/2 - θ) = cosec θ) =\(\cfrac{-sin(2\pi-t)}{cosec\, t} \) (∵ sin (-θ) = -sinθ) = \(\cfrac{-(-sin\,t)}{cosec\, t} \) (∵ sin (2π - θ) = -sinθ) = sin t / cosec t = sin t sin t \((∵\cfrac{1}{cosecθ}=sinθ)\) = sin² t Hence, \(\cfrac{sin(t-2π)}{sec(\frac{\pi}2-t)}=sin^2 t\)

46.

Find:\(\cfrac{sin(t - 2 \pi)}{sec(\frac{\pi}{2}-t)} \)

Answer»

\(\cfrac{sin(t - 2 \pi)}{sec(\frac{\pi}{2}-t)} \) = \(\cfrac{sin(-(2\pi-t))}{cosect}\) (∵ sec (π/2 - θ) = cosec θ)

=\(\cfrac{-sin(2\pi-t)}{cosec\, t} \) (∵ sin (-θ) = -sinθ)

= \(\cfrac{-(-sin\,t)}{cosec\, t} \) (∵ sin (2π - θ) = -sinθ)

= sin t / cosec t

= sin t sin t \((∵\cfrac{1}{cosecθ}=sinθ)\)

= sin² t

Hence, \(\cfrac{sin(t-2π)}{sec(\frac{\pi}2-t)}=sin^2 t\)
