Trigonometric Functions
Master Trigonometric Functions in Grade 10 math: calculate periods, key points, and asymptotes using the y=a·tan(bx) formula with Saxon Algebra examples.
Key Concepts
The sine, cosine, and tangent of angle $A$ are defined as: $$\sin A = \frac{\text{opp}}{\text{hyp}}$$ $$\cos A = \frac{\text{adj}}{\text{hyp}}$$ $$\tan A = \frac{\text{opp}}{\text{adj}}$$.
For a right triangle with side opposite $\angle A$ as 5, adjacent as 12, and hypotenuse 13: $\sin A = \frac{5}{13}$. For the same triangle, the cosine is: $\cos A = \frac{12}{13}$. And the tangent for that same angle is: $\tan A = \frac{5}{12}$.
Just remember the secret code SOH CAH TOA! These are special ratios that connect an angle's measure to the lengths of a right triangle's sides. They're the key to solving for missing pieces.
Common Questions
