Answer:
2 / √( 1 - 4x² )
Step-by-step explanation:
To find -----> Derivative of Sin⁻¹ ( 2x )
Solution------> We know that,
1) d/dx ( Sin⁻¹x ) = 1 / √1 - x²
2) d/dx ( x ) = 1
ATQ,
y = Sin⁻¹ ( 2x )
Differentiating with respect to x ,
=> dy/dx = d/dx ( Sin⁻¹ 2x )
= [ 1 / √{ 1 - ( 2x )² ] d/dx ( 2x )
= 1 / √( 1 - 4x² ) ( 2 × 1 )
= 2 / √( 1 - 4x² )
Additional information----->
1) d/dx ( xⁿ ) = n xⁿ⁻¹
2) d/dx ( eˣ ) = eˣ
3) d/dx ( aˣ ) = aˣ loga
4) d/dx ( logx ) = 1 / x
5) d/dx ( Sinx ) = Cosx
6) d/dx ( Cosx ) = - Sinx
7) d/dx ( tanx ) = Sec²x
8) d/dx ( Secx ) = Secx tanx
9) d/dx ( Cotx ) = - Cosec²x
10) d/dx ( Cosecx ) = - Cosecx Cotx
