question 71

Multiple Choice

Solve the initial value problem.
- $$\frac { d y } { d x } = e ^ { 7 x } \cos e ^ { 7 x } , y ( 0 ) = 0$$

• A) \(y = \frac { 1 } { 7 } \sin \mathrm { e } ^ { 7 \mathrm { x } } - \frac { 1 } { 7 }\)
• B) \(y = \frac { 1 } { 7 } \sin x\)
• C) \(\mathrm { y } = - \frac { 1 } { 7 } \sin \mathrm { e } ^ { 7 \mathrm { x } } + \frac { 1 } { 7 } \sin 1\)
• D) \(y = \frac { 1 } { 7 } \sin \mathrm { e } ^ { 7 x } - \frac { 1 } { 7 } \sin 1\)
