Webb\Phi=B A \cos (\theta) $ Where: $\theta=$ angle between magnetic field lines and the line perpendicular to the plane of the area (often called the normal line) (degrees) This means the magnetic flux is: Maximum $=B A$ when $\cos (\theta)=1$ therefore $\boldsymbol{\theta}=0 ... A small rectangular coil contains 350 turns of wire. The … WebbThe cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. It is the complement to the sine. In the …

For small angles sin(theta)=theta.Why? - BYJU
The small-angle approximations can be used to approximate the values of the main trigonometric functions, provided that the angle in question is small and is measured in radians: Visa mer Graphic The accuracy of the approximations can be seen below in Figure 1 and Figure 2. As the measure of the angle approaches zero, the difference between the approximation and the original … Visa mer Astronomy In astronomy, the angular size or angle subtended by the image of a distant object is often only a few Visa mer Figure 3 shows the relative errors of the small angle approximations. The angles at which the relative error exceeds 1% are as follows: • cos θ ≈ 1 at about 0.1408 radians (8.07°) • tan θ ≈ θ at about 0.1730 radians (9.91°) Visa mer • Skinny triangle • Infinitesimal oscillations of a pendulum • Versine and haversine Visa mer WebbGiven, Angle between ladder and ground, and distance from ladder to wall = 10 ft. As we know, ∴ The height of the wall up to which the ladder reaches is 20 ft. FAQs Explain how … WebbThe small angle approximations, as given in the Edexcel Formula Booklet, are: sin ( θ) ≈ θ cos ( θ) ≈ 1 − θ 2 2 tan ( θ) ≈ θ These approximations can only be used when θ is small. … popular hobbies in spain
