" 4.Find tan "15^(@)" and hence show that "tan15^(@)+cot15^(@)=4

Find tan15^(@) and hence show that tan15^(@)+cot15^(@)=4

Find tan 15^(@) and hence show that tan 15^(@) + cot 15^(@) =4 .

Find tan 15^@ and hence show that tan 15^@+ cot 15^@ = 4 .

Show that tan 15^@ + cot 15^@ = 4

tan15^(@) + tan 75^(@)=

Prove that (tan75^(@))/(cot15^(@))=1

Show that tan 15^@ + tan 75^@ = 4

Evaluate tan15^@

If tan 15^(@) = 2 - sqrt(3) , then show that 2 tan 1095^(@) + cot 975^(@) + tan (-195^@) = 4 - 2sqrt(3) .
