`(cot1 8^(@))/(tan7 2^(@))`

The value of cot7(1^(0))/(2)+tan67(1^(@))/(2)-cot67(1^(@))/(2)-tan7(10)/(2)

The value of cot7(1^0)/2+tan67(1^(@))/2-cot67(1^(@))/2-tan7(1^0)/2 is

cot theta=(2tan7(1)/(2^(@)))/(1-tan^(2)7(1)/(2^(@))) then sin3 theta=

cot5^(@)-tan5^(@)-2tan10^(@)-4tan20^(@)-8cot40 is equal to -

(sec 8 A-1)/( sec 4A-1)= ..................... A) (tan 2A)/( tan 8A) B) (tan 8A)/(tan 2A) C) (cot 8A)/(cot 2A) D) (tan 6A)/(tan 2A)

Find the value of tan^(-1)((1)/(2)tan2A)+tan^(-1)(cot A)+tan^(-1)(cot^(3)A)

((1+tan^(2)A)/(1+cot^(2)A))=((1-tan A)/(1-cot A))^(2)=tan^(2)A

Show that ((1+tan ^(2) A) /(1+cot ^(2) A ) ) =((1+ tan )/( 1-cot A ))^(2)= tan ^(2) A

Show that ((1+tan ^(2) A) /(1+cot ^(2) A ) ) =((1+ tan )/( 1-cot A ))^(2)= tan ^(2) A

Prove that (1+tan^(2)A)/(1+cot^(2)A)=((1-tan A)/(1-cot A))^(2)=tan^(2)A
