These all seem good to have, but I have questions about the colour of the bikeshed names
|
@Ruben-VandeVelde are you okay with the new names? |

… cpow (#19944) * Add several results that exists for `rpow` but not for `cpow`: - * `DifferentiableAt.cpow_const`, `DifferentiableWithinAt.cpow_const` and `DifferentiableOn.cpow_const` about the differentiability of `z ↦ (f z) ^ c` - * `Complex.deriv_cpow_const` and `deriv_cpow_const` for computing `deriv` * Add also an alternate version of `hasDerivAt_ofReal_cpow` on the differentiability of `fun y : ℝ => (y : ℂ) ^ c` and the corresponding `DifferentiableAt` and `deriv` results that follow. * Add the equivalent for `fun y : ℝ => (y : ℂ) ^ c` of `isTheta_deriv_rpow_const_atTop` and `isBigO_deriv_rpow_const_atTop` This PR doesn't add new maths since all the results proved are direct consequences of existing results.
