Indefinite IntegrationHard
Question
If 
dx = K sin-1 (2x) + C, then the value of K is equal to
dx = K sin-1 (2x) + C, then the value of K is equal to Options
A.ln 2
B.
ln 2
ln 2C.
D.
Solution
Let 2x = t ⇒ 2x log2 dx = dt
∴ I =
sin-1(t) + C = 
sin-1(2x) + C
∴ K =
∴ I =
sin-1(t) + C = sin-1(2x) + C ∴ K =
