Correct Answer: $\frac{15}{8}$

Solution : Given: $\sec A=\frac{17}{15}$
$⇒\cos A = \frac{15}{17}$
$⇒\sin A = \sqrt{1-\cos^2 A}= \sqrt{1-(\frac{15}{17})^2}$ = $\sqrt{\frac{64}{289}}$ = $\frac{8}{17}$
$\therefore \cot A = \frac{\cos A}{\sin A} = \frac{\frac{15}{17}}{\frac{8}{17}} = \frac{15}{8}$
Hence, the correct answer is $\frac{15}{8}$.

Hello aspirant,

Astronomy is a branch of natural science that investigates celestial bodies, as well as the forces that arise from their interactions in space and other visible phenomena. In addition to astronomy, space sciences comprise other fields of study such as space travel and space exploration. So both these

Hello,

You can consider opting for the following universities with its respective courses abroad at undergraduate level-

• University of Kent, UK; BSc Hons Astronomy, Space Science and Astrophysics
• University of Leicester, UK; BSc Hons Physics with Space Science
• University College Dublin, Ireland    BSc (Hons) in Physics with Astronomy and Space

See if you wish to go for the Space science, then formally there are no courses available which offers directly Msc in space science. Some of the courses involving space science in MSc courses is mainly Astrophysics. Now for the Astrophysics most university prefers a Physics degree.

I would suggest
