TRIGONOMETRIC IDENTITIES TRIGONOMETRY: What exactly is trigonometry? Trigonometry is primarily concerned with angles and triangles.The study of angles and how they affect various quantities and measures is known as trigonometry.Trigonometry is used to learn about triangles and their relationships What are the trigonometric applications? The trigonometric method is used to determine the height of a building or mountain, as well as the length of a beam required to span a specific distance. The trigonometry method is used to calculate an object's torque and forces.Engineers use trigonometric methods to solve design and construction problems involving structures such as bridges and buildings. A navigation method that calculates the distance between a receiver and a satellite using the law of cosines. Trigonometric methods are used by astronomers to calculate the distances of stars and planets from Earth. Physicists use trigonometry to study wave behaviour, analyse signals, and predict ...

 

  WHAT IS TORQUE? GIVE E XAMPLES             TORQUE: The force(torque) is a winding power(twisting force) follows up on an article that produces revolution of an item and is given by the cross result( product ) of position vector and the force vector. EXAMPLES: Opening/closing the door: The most well-known perspective of a force(torque) is to consider a door.The simplest method of opening an entryway is to apply a force on the super side of the entryway inverse to the pivots and push/pull the entryway with a base power opposite the entryway. Using wrench: At the point when we apply power to the handle of a wrench, the applied power makes a force(torque) on the drag nut..More force can be applied by adding more weight or by utilizing a more extended wrench. Car engine creates torque To control and stabilize aircraft.  

  FACTORS THAT AFFECT THE FLIGHT OF A PROJECTILE: Projection point(angle) : The article is leaned at a point to the vertical or flat (horizontal) (close to the earth) The mass of the article: The flight condition incorporates no data about the item size, shape, or mass. Dispatch speed:  Maximum stature (height) changes as the square of the dispatch speed (launch velocity). Multiplying the dispatch speed creates multiple times the greatest stature. Gravitational speed increase:  It is the rate at which an article's speed is evolving. The change can be the means by which quick the article is moving,a bearing change or both. Air opposition:  Effects will be disregarded. The drag of the air: Drag relies upon air thickness and the square of the velocity.If the drag is overlooked, the flight relies upon starting speed and speed increase due to gravity(near the earth).
