To differentiate [itex]cos(yz^{2})[/itex] with respect to y
can we simply ignore the [itex]z^{2}[/itex] term in the differentiation ?

The formula for differentiating cos(yz^2) is -yz^2sin(yz^2).
The chain rule is used to differentiate the inner function, which in this case is yz^2. It allows us to break down the function into smaller, more manageable parts.
No, the power rule can only be used for functions with a constant as the base. In this case, the base is not a constant but a variable, z.
To differentiate cos(yz^2) with respect to y, we use the product rule. The derivative will be -z^2sin(yz^2).
Yes, if we rewrite cos(yz^2) as cos(z^2)y, then the derivative will be -z^2sin(z^2)y.
