Question

Solve the trigonometric equation for all values: -7 < or equal to x < 7 Question: Cot 1/2x-1=0

Answer 1

x =90

Explanation:

Cot 1/2x-1=0

Add 1 to both sides

Cot 1/2x = 0+1

Cot 1/2x = 1

1/tan1/2x = 1

Tan 1/2x = 1

1/2x = arctan1

1/2x =45

x = 45×2

x = 90

Hence the value of x is 90
