Performing Advanced Calculations

Google's calculator isn't limited to basic addition and multiplication. It can also handle more advanced calculations (detailed in Table 14.2), trigonometric functions (Table 14.3), inverse trigonometric functions (Table 14.4), hyperbolic functions (Table 14.5), and logarithmic functions (Table 14.6). If you know what these functions are, I assume you know the proper way to use them. If you don't, then get yourself a good math book or don't bother with them.
