Question

verify that tan45/cosec30+sec60
/cot45-2sin90/cos0=1/2
​

Answer 1

Step-by-step Explanation:

Tan 45 = 1

Cosec 30 = 2

Sec 60 = 2

Cot 45 = 1

Sin 90 = 1

Cos 0= 1

Therefore....

Substituting the following values in the given equation

→Tan 45/Cosec 30 + Sec 60/Cot 45 - 2 Sin 90/ Cos 0 = 1/2

→1/2 + 2/1 -2*1/1

finding the LCM= 2

→1/2 + 4/2 - 4/2

→Therefore the resultant is 1/2

This resultant is equal to the value of the RHS
