WebTaking the [principal] square root of both sides yields: sin x = 3/5. [Remember that √ (x²) = x , not x, not ±x, and x = c means x = ±c for c > 0.] Therefore, sin x = ±3/5 is the final … WebQuestion bank on Definite & Indefinite Integration There are 168 questions in this question bank.

WebFind the possible values of $\sin\theta$ and $\tan\theta$, given that $\cos\theta = 3/5$ and $0 \leq \theta \leq \pi/2$. Here is my working out: Using a right hand triangle: $$\cos\theta =a/c$$... Stack Exchange Network Web∴ sin 90° = sin (1.5707) = 1 Explanation: For sin 90 degrees, the angle 90° lies on the positive y-axis. Thus, sin 90° value = 1 Since the sine function is a periodic function, we can represent sin 90° as, sin 90 degrees = sin (90° + n × 360°), n ∈ Z. ⇒ sin 90° = sin 450° = sin 810°, and so on.
