This is Grade 9 Mathematics so I kinda stuck here so, if somebody can help me Please sin30⁰+csc60⁰

mamaluj [8]

$\huge\mathrm{Answer࿐}$

$\sin(30) + \csc(60)$

$\dfrac{1}{2} + \dfrac{2}{ \sqrt{3} }$

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} }$

To remove √3 from denominator, we multiply both numerator as well as denominator with √3

$\dfrac{ \sqrt{3 } + 4 }{2 \sqrt{3} } \times \dfrac{ \sqrt{3} }{ \sqrt{3} }$

$\dfrac{3 + 4 \sqrt{3} }{6}$

jarptica [38.1K]

Here y=1/2 x=pi/3=60°

y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS

so that point is on curve y=cosx
