Ek baar sir se confirm kr lo tmhara answer abhi bhi sahi nahi hai ku ki cos^3(x) raheta tb 3 bahar aa kr multiply ho jata lakin tmhara question me cos x^3 hai or x jo hai wo ek angle hai or cos ka function hai isliye cos x^3 ka differentiation-sin x^3 hoga Because differentiation of cos x is - sin x

Log ka function hai sin x cos^3x is liye uska differetation hoga 1/sin xcos^3x Uske baad sin(x) ka differentiation hoga cos(x) or uske baas cos^3(x) ka hoga -2sin^2(x) uske baad usko simply solve kr do aa jayega answer

Derivation of all formula of motion of constant acceleration

Posted by Jack Jack 6 years, 4 months ago

Sia ? 6 years, 4 months ago

From the definition of average acceleration, we have
{tex}a = \frac { d v } { d t } \Rightarrow d v = a d t{/tex}
Integrating on both sides and taking the limit for velocity u to v and for time 0 to t, we get
{tex}\int _ { u } ^ { v } d v = \int _ { 0 } ^ { t } a d t = a \int _ { 0 } ^ { t } d t = a [ t ] _ { 0 } ^ { t }{/tex}[a is constant]
v - u = at
v = u + at .....................(i)
Now, from the definition of velocity, we have

{tex}v = \frac { d x } { d t } \Rightarrow d x = v d t{/tex}
Integrating on both sides and taking the limit for displacement x₀ to x and for time 0 to t, we get
{tex}\int _ { x _ { 0 } } ^ { x } d x = \int _ { 0 } ^ { t } v d t = \int _ { 0 } ^ { t } ( u + a t ) d t = v _ { 0 } [ t ] _ { 0 } ^ { t } + a \left[ \frac { t ^ { 2 } } { 2 } \right] _ { 0 } ^ { t }{/tex}
x - x₀ = ut + {tex}\frac 12{/tex}at²
x = x₀ + ut + {tex}\frac 12{/tex}at² ..........................(ii)
Now, we can write
{tex}a = \frac { d v } { d t } = \frac { d v } { d x } \frac { d x } { d t } = v \frac { d v } { d x }{/tex} or vdv = adx
Integrating on both sides and taking the limit for velocity u to v and for displacement x₀ to x, we get
{tex}\int _ { u } ^ { v } v d v = \int _ { x _ { 0 } } ^ { x } a d x{/tex}; {tex}\frac { v ^ { 2 } - u ^ { 2 } } { 2 } = a \left( x - x _ { 0 } \right){/tex}
v² = u² + 2a(x - x₀) ........................(iii)
Equations (i), (ii) and (iii) are the required equations of motion.
