WebWe know. The angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30. WebMathematically, the cosine function formula in terms of sides of a right-angled triangle is written as: cos x = Adjacent Side/Hypotenuse = Base/Hypotenuse, where x is the acute angle between the base and the hypotenuse.

Since cosine function is positive in the first quadrant, thus cos 60° value = 1/2 or 0.5. Since the cosine function is a periodic function, we can represent cos 60° as, cos 60 degrees = cos (60° + n × 360°), n ∈ Z. ⇒ cos 60° = cos 420° = cos ... flutter text headingWebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0.
