sinθ/cosθ
The expression sinθ/cosθ is a trigonometric expression that involves the sine (sin) and cosine (cos) functions
The expression sinθ/cosθ is a trigonometric expression that involves the sine (sin) and cosine (cos) functions. To simplify this expression, we can recall a fundamental trigonometric identity called the tangent identity.
The tangent identity states that:
tanθ = sinθ / cosθ
By rearranging the terms, we can find the equivalent expression for sinθ / cosθ in terms of tangent:
sinθ / cosθ = (1 / cosθ) * sinθ
= tanθ
Therefore, the expression sinθ / cosθ simplifies to tanθ, which represents the tangent of angle θ. In other words, if you want to find the value of sinθ / cosθ, you can directly calculate the tangent of θ instead.
