Q. Prove the following :

(i) sin θ sin (90° − θ) − cos θ cos (90° − θ) = 0
(ii)

\frac{\cos (90 ° - θ) \sec (90 ° - θ) \tan θ}{cosec (90 ° - θ) \sin (90 ° - θ) \cot (90 ° - θ)} + \frac{\tan (90 ° - θ)}{\cot θ} = 2

\frac{\tan (90 ° - A) \cot A}{{cosec}^{2} A} - \cos^{2} A = 0

\frac{\cos (90 ° - A) \sin (90 ° - A)}{\tan (90 ° - A)} = \sin^{2} A

(v) sin (50° − θ) − cos (40° − θ) + tan 1° tan 10° tan 20° tan 70° tan 80° tan 89° = 1

Q. The value of

\frac{cos θ}{sin (90^{0} + θ)} + \frac{sin θ}{sin (180^{0} + θ)} + \frac{cot (90^{0} - θ)}{tan θ}

x cot (90 + θ) + tan (90 + θ) s i n θ + cos e c (90 + θ) = 0

x sin (90^{0} - θ) cot (90^{0} - θ) = cos (90^{0} - θ)
