Given, Angle between ladder and ground, and Hypotenuse = 44 ft. As we know, ∴ The height of the wall is feet. FAQs Explain how sin (-x) = -sin (x). As we know, the angle (-x) lies in the 4th quadrant of a graph, and sine is negative in this quadrant. Hence, this shows that sin (-x) = -sin (x). What is sin theta?

WebAs you already know how to write Sin Θ, Cos Θ and Tan Θ, the reciprocal of these ratios will become Cosec Θ, Sec Θ and Cot Θ and these are defined as follows - Cosec Θ = Hypotenuse / Opposite Side Sec Θ = Hypotenuse / Adjacent Side Cot Θ = Adjacent Side / Opposite Side Lets study some examples on how to write Cosec Θ, Sec Θ and Cot Θ Web25 Jan 2024 · The word cosinus derived from Edmund Gunter. In \ (1674\), the English Mathematician Sir Jonas Moore first used the abbreviated notation ‘cos’. Sin, Cos: Formula Let us take a right-angled triangle \ (\Delta PQR\) as shown. Here, \ (\angle RPQ\) or \ (\angle P\) is an acute angle. The side \ (QR\) is facing \ (\angle P\).
