 \frac{cos \: a}{cot \: a}  + sin \: a \\  =  \frac{cos \: a}{ \frac{cos \: a}{sin \: a} }  +  \: sin \: a \\  = sin \: a \:  + sin \: a \\  = 2sin \: a

Step-by-step explanation:

 \frac{ \cos(a) }{ \cot(a) }  +  \sin(a)  \\ write \:  \cot(a) in \: the \:terms \: of \:  \\ sin \: and \: cos \\  \frac{ \cos(a) }{ \frac{ \cos(a) }{ \sin(a) } }  +  \sin(a)  \\  \sin(a)  +  \sin(a)   = 2 \sin(a)

this is the required answer

Hope you get it
