If l_1= d dx ( ^ x ) aligned & l_2= _ h arrow 0 ^ (x+h) - ^ x h &...
If $$
then which one of the following is correct?
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
l_3=\int \mathrme^{\sin \mathrm{x}} \cdot \cos \mathrm{xdx}\sin \Rightarrow \cos l_3=\int \mathrme^{\mathrm{t}} \cdot \mathrm{dt}=\mathrme^{\mathrm{t}}+\mathrm{c}=\mathrme^{\sin \mathrm{x}}+\mathrm{c}\frac{\mathrm{d}}{\mathrm{dx}}$\left(l_3\right)=\frac{\mathrm{d}}{\mathrm{dx}}\left(\mathrme^{\sin \mathrm{x}}+\mathrm{c}\right)=\frac{\mathrm{d}}{\mathrm{dx}}\left(\mathrme^{\sin \mathrm{x}}\right)=l_1=l_2
