Answer: You can solve this by splitting. Then solve the parts of the integration and you’ll get the right result. ItR..
Answer: You can use the method of parts by taking secx as u and sec^2 as dv/dx. Here’s how to do that: first, apply integral reduction. Then, rewrite the integrand and expand the function tan(x)+sec(x). Apply u-substitution with u, then undo it and plug in solved integrals. Finally, you need to add the constant of ..
Answer: You’re almost 5 feet 2 inches tall or 5 feet 1 and 4/5 inches to be precise. ItR..
Answer: An angle of 2π rads us 1 revolution so 6π is 3 revolutions. cos(0) = 1, cos(2π) = 1, cos(6π) = 1. An angle of π/2 is a quarter turn or right angle anticlockwise so an angle of – π/2 is a quarter turn or right angle clockwise. Therefore, 11π/2 is 11 right angles ..
Answer: You can look it up on Research gate where Tadeusz Ostrowski dedicates a chapter to diagonalization applications. But the first thing that comes to my mind is Markova processes because there are many cases where square matrix are used. For example, they help in calculating frequencies in mechanics, acoustic frequencies and principal moments of ..
Answer: There’s a math module in python and it can do math.factorial(x). If you want, though, you can construct the module yourself but don’t try it if you haven’t got enough experience. But all this sound like asking to do your homework. If you really don’t know how to do that rephrase the question, please. ..
Answer: For some reason, it’s not allowed to make an integral sign of the same size as your expression. There’s only one thing you can do if you want to change the size: type: “\left[ … \right] \left( … \right)”. ItR..
Answer: Let’s go to basics, what is sin(θ). Sin(θ) is the ration of opposite side to hypotenuse. In above figure B angle = 90°, now the opposite side is AC and even hypotenuse is AC. Sin(θ) = opposite/hypotenuse = AC/AC = 1. ItR..
Answer: This term was created by Arthur Schuster in 1898 and it’s a component of other methods. It expresses signal’s spectral density. It doesn’t require analysis of sinusoid signals at low signal-to-noise ratios. But there are still moiseless responses and other signals that need a more precise estimation. There are 2 ways of using periodograms: ..
Answer: It’s very important to remember these values. If you don’t know them you won’t be able to say the value of cos 0°. You can create a table with angles (in degrees) and several columns: sin, cos, tan, sec, cosec and cot. You can learn the values of sine or cosine because they represent ..
