So basically you're dividing 12 by 3 times x which is 12 over 3x. 12/3x

Volume of a sphere = 4/3(3.14)(2.6)^3
Raise 2.6 to the third power and substitute it in the equation
Multiply that number by 3.14
Whatever your answer is, times it by 4
Then divide that answer by 3
Hope this helps !
The answer is cot² ∅ - csc² ∅ = -1
Referring to Pythagorean identities:
sin² ∅ + cos² ∅ = 1
1+cot² ∅ = csc² ∅
tan² ∅ + 1 = sec² ∅
1+cot² ∅ = csc² ∅
⇒ transposing 1 and csc² ∅ we will have now
cot² ∅ - csc² ∅ = -1
