Answer:
see below
Step-by-step explanation:
sin x cos x = cot x
We need to show a counter example
Let's use 30 degrees
sin 30 cos 30 = cot 30
1/2 * sqrt(3) /2 = sqrt(3)
sqrt(3)/4 = sqrt(3)
not true
Answer:
Step-by-step explanation:
sin(60) = sqrt(3)/2
cos(60) = ½
tan(60) = sqrt(3)
cot(60) = 1/sqrt(3) = sqrt(3)/3
sin(60) cos(60) = cot(60)
sqrt(3)/2 × ½ = sqrt(3)/3
sqrt(3)/4 = sqrt(3)/3
Is a FALSE statement.
So the equation is not true for x = 60. Hence, not an identity
