The sine of s is 1/2 and the cosine of s -v3/2. Which is the contangent of s

Question

a) √3/2

b) √3

c) -√3/2

d) -√3

Answer 1

Hi Johny, for this question the trick is to remember what tangent and cotangent are, in terms of sine and cosine. Remember that tangent is sin/cosine, and that cotangent is 1/tangent. This means that cotangent is also cosine/sine. 

 

So, the cotangent of s will be[ -√(3/2)] / [1/2] 

 

Hope this helps!
