Manipur Board Solutions for Chapter: Trigonometry, Exercise 3: EXERCISE 10.3

Find the value of $\frac{\tan 49°}{\cot 41°}$

Find the value of $\frac{\cos 70°}{\sin 20°}$

Find the value of $\frac{\tan 26°}{\cot 64°}$

Find the value of $\frac{\mathrm{cosec}35°}{\sec 55°}$

Find the value of $\cos 37°-\sin 53°$

Find the value of $\mathrm{cosec}47°-\sec 43°$

Show that $\sec 53°\sin 53°\tan 37°=1$

Compare the areas of the right angles $ABC\hspace{0.17em}\& DEF$ in which $A=\angle 40°, \angle B=90°, AC=5 cm: \angle D=50°, \angle E=90° \& DE=5 cm$.

Use $\cos 40°=0.766, Sin40°=0.642 \& \tan 40°=0.84$.
