Question

evaluate cot 34 and tan 56​

Answer 1

Answer:cot340−tan560=0.

Step-by-step explanation:

Consider cot340 which can be rewritten as follows:

cot340=cot(900−560)=tan560(∵cot(900−x)=tanx)

 

Therefore, cot340−tan560 can be evaluated as shown below:

     

cot340−tan560=tan560−tan560=0  

     

Hence, cot340−tan560=0.

Answer 2

Answer:

Step-by-step explanation:Given

= Cot 34 - tan 56

Cot34 = Cot (90-56)

= tan 56

by substituting the cot 34 value in the given ques

we get,

= tan56- tan56
