1.	In the table, trigonometric ratios and the intervals of θ are given. Match the intervals with the ratios which are positive in those intervals. θgives positive valuesp. (0,π2)1. Only sin θ,cosec θq. (π2,π)2. Only cos θ,sec θr. (π,3π2)3. Only tan θ,cot θs. (3π2,2π)4. All sin θ,cos θ,tan θ,cot θ,sec θ,cosec θ
Answer» In the table, trigonometric ratios and the intervals of $θ$ are given. Match the intervals with the ratios which are positive in those intervals. $\begin{matrix} θ & gives positive values p. (0, \frac{π}{2}) & 1. Only sin θ, cosec θ q. (\frac{π}{2}, π) & 2. Only cos θ, sec θ r. (π, \frac{3 π}{2}) & 3. Only tan θ, cot θ s. (\frac{3 π}{2}, 2 π) & 4. All sin θ, cos θ, tan θ, cot θ, sec θ, cosec θ \end{matrix}$
