find the values of the six trigonometric functions for angle theta in standard position if a point with the coordinates (1, -8) lies on its terminal side

cosФ = , sinФ = , tanФ = -8, secФ = , cscФ = , cotФ =

Step-by-step explanation:

If a point (x, y) lies on the terminal side of angle Ф in standard position, then the six trigonometry functions are:

∵ Point (1, -8) lies on the terminal side of angle Ф in standard position

∵ x is positive and y is negative

→ That means the point lies on the 4th quadrant

∴ Angle Ф is on the 4th quadrant

∵ In the 4th quadrant cosФ and secФ only have positive values

∴ sinФ, secФ, tanФ, and cotФ have negative values

→ let us find r

∵ r =

∵ x = 1 and y = -8

∴ r =

→ Use the rules above to find the six trigonometric functions of Ф

∵ cosФ =

∴ cosФ =

∵ sinФ =

∴ sinФ =

∵ tanФ =

∴ tanФ = = -8

∵ secФ =

∴ secФ = =

∵ cscФ =

∴ cscФ =

∵ cotФ =

∴ cotФ =

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
