Question

if tan 15= 2-√3 ,find the value of tan 7.5​

Answer 1

Answer:

Firstly It Should be tan75

But if it is tan7.5 then tan 7.5=0.13165249758

We Know that tan15=cot75  (because tan and cot are complementary to each other)

=>cot75=$2-\sqrt{3}$

We Also Know That tan and cot are inverse ratios of each other

=>tan75=1/2-$\sqrt{3}$
