So I am wanting to check whether or not I have done the correct differentiation of the following function:
$$\sin(\log({\mathbf t^T}{\mathbf t})) \quad \text{where } \mathbf t \in R^D$$
Obviously using the chain rule I have ended up with the following:
$$\frac{2\mathbf t}{{\mathbf t^T}{\mathbf t}}\cos(\log({\mathbf t^T}{\mathbf t}))$$
Please note that the bold is signifying vectors. If I have done this wrong should I instead be computing the Jacobian?
