Here, we show you a step-by-step solved example of simplify trigonometric expressions. This solution was automatically generated by our smart calculator: $\frac {1-sin\left (x\right)^2} {csc\left (x\right)^2-1}$ Applying the trigonometric identity: $\csc\left (\theta \right)^2-1 = \cot\left (\theta \right)^2$
Rewrite the cosine function in terms of the sine function. Here, the rewrite function rewrites the cosine function using the identity cos (x) = 1-2 sin (x 2) 2, which is valid for any x.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
For example, the equation (sin x + 1) (sin x − 1) = 0 (sin x + 1) (sin x − 1) = 0 resembles the equation (x + 1) (x − 1) = 0, (x + 1) (x − 1) = 0, which uses the factored form of the difference of squares. Using algebra makes finding a solution straightforward and familiar.
The values of the 6 trig functions for 90 degrees (π/2) are the following ones: sin(90°) = 1; cos(90°) = 0; tan(90°)= undefined; cot(90°) = 0; sec(90°) = undefined; and; csc(90°) = 1.
19 lut 2024 · Prove: 1 + cot2θ = csc2θ. 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side. = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with the common denominator. = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ. Similarly, 1 + tan2θ = sec2θ can be obtained by rewriting the left side of this identity in terms of sine and cosine. This gives.
