$\frac{d}{{dx}}\,\,\left( {\cos \,\,4{x^2}} \right)\,\,\,$ નું મૂલ્ય ....... થાય .
A$- 2x sin 4x^5$
B$- 5x sin 3x^2$
C$- 7x sin 4x^3$
D$- 8x sin 4x^2$
Solution
$\frac{d}{{dx}}\,\,\left( {\cos \,\,4{x^2}} \right)\,\, = \,\, – \sin \,\,4{x^2}\,\,\left[ {\frac{d}{{dx}}\left( {4{x^2}} \right)} \right]\,\, = \,\, – 8x\,\,\sin 4{x^2}$
