प्रश्न
Find the degree measure corresponding to the following radian measure.
`pi/8`
उत्तर
We know that, one radian = `180^circ/pi`
`pi/8 = 180^circ/pi xx pi/8` degrees
`= 45/2`
= 22.5°
= 22°30′ .....[∵ 0.5° = (0.5 × 60)’ = 30′]

Find the values of the following trigonometric ratio.
cos (-210°)
Prove that:
`(sin(180^circ - theta)cos(90^circ + theta)tan(270^circ - theta)cot(360^circ - theta))/(sin(360^circ - theta)cos(360^circ + theta)sin(270^circ - theta)cosec (-theta))` = -1
Prove that:
`sin theta * cos theta {sin(pi/2 - theta) * "cosec" theta + cos (pi/2 - theta) * sec theta}` = 1
If α and β be between 0 and `pi/2` and if cos(α + β) = `12/13` and sin (α – β) = `3/5` then sin 2α is:
`sin (cos^-1 3/5)` is
