Help me please, I have no idea how to do these:
1. Approximate the value of sin(32degrees)
2. Use differentials to approximate Arctan 1.1
Thank you!
What about using ?
You know the exact values of and , and perhaps you also know that for small angles (expressed in radians) you have and .
So set and plug those two approximations into the above expression for .
Just use , with , for .2. Use differentials to approximate Arctan 1.1
