To find tan alpha and sin alpha, we can use the trigonometric identity tan^2 alpha + 1 = sec^2 alpha. By substituting the value of cos alpha, we can find sin alpha.

To find tan alpha and sin alpha, we can use the trigonometric identity:

tan^2 alpha + 1 = sec^2 alpha

We know that cos alpha = sqrt(3)/3. We can use this information to find sin alpha as follows:

sin^2 alpha + cos^2 alpha = 1

sin^2 alpha + (sqrt(3)/3)^2 = 1

sin^2 alpha + 3/9 = 1

sin^2 alpha = 1 - 3/9

sin^2 alpha = 6/9 - 3/9

sin^2 alpha = 3/9

sin alpha = sqrt(3)/3

The probable question may be:

Find tan alpha and sin alpha, if cos alpha=\sqrt3/3
