Components
This is a powerful opensource android calculator that contains almost of the features needed. But this simple calculator lags a simple inverse functions of sin,cos,tan
Proposal
My proposal is add the inverse functions of sin,cos,tan where user can perform the inverse function in this same calculator itself
Mockups / Examples
when user holds the sin the sin-1 function will be enabled where same goes to other two
Benefits
Inverse of sin,cos,tan can be perform
