Trigonometry Trigonometry uses the fact that ratios of pairs of sides of triangles are functions of the angles. The basis for mensuration of triangles is the right- angled triangle. The term trigonometry means literally the measurement of triangles. Trigonometry is a branch of mathematics that developed from simple measurements. A theorem is the most important result in all of elementary mathematics. It was the motivation for a wealth of advanced mathematics‚ such as Fermat’s Last Theorem

The two pictures below demonstrate the calculations from Trial 1 at 0° and Trial 1 at 45°. In this experiment we did five separate shots from the cannon at 0°‚ and 3 separate shots at 45°. We determined the average distance of the shots from each angle by using a meter stick. We were then able to calculate the velocity of the shots by dividing the time from distance. After getting the results‚ the distance from the shots fired at 45° had a greater distance from the shots fired at 0° horizontally

instrument s”. He said “you should play cymbals”. I immediately joined again. On my first day I had to learn the three basic skills on cymbals choke chase and crash. First was the crash. Crashing the cymbals you had to hold the left or right at an angle the hit it with the other. I could do this step it was the easiest. I never could mess up this step. Crash‚ crash‚ crash‚ one after another left then right then again. Most people that first learn the cymbals this step should come naturally. Next

e.‚ y = mx Question 4: Find the equation of the line which passes though and is inclined with the x-axis at an angle of 75°. Answer : The slope of the line that inclines with the x-axis at an angle of 75° is m = tan 75° We know that the equation of the line passing through point ‚ whose slope is m‚ is . Thus‚ if a line passes though and inclines with the x-axis at an angle of 75°‚ then the equation of the line is given as Question 5: Find the equation of the line which intersects

rigidly held and supported in a tool post which is fed against the revolving work. The normal cutting operations are performed with the cutting tool fed either parallel or at right angles to the axis of the work. The cutting tool may also be fed at an angle relative to the axis of work for machining tapers and angles. To get the desired shape of a work piece a lathe machine is used and the processes involved to set up the final product are as follows: Job setting Facing Plane turning
