To add two vectors using trigonometry, you can use the Law of Cosines. This states that the square of the resultant vector's magnitude is equal to the sum of the squares of the individual vectors' magnitudes, minus two times the product of their magnitudes and the cosine of the angle betw...
from the trigonometry table, use the value of sin 60° which is equal to √3/2. hence, the value of sin 120 degrees is √3/2 method 2 by using the value of cosine function relations, we can easily find the value of sin 120 degrees. using the trigonometry formula, sin (90 + a)...
if the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i.e., the value of cos 30 degree is in a fraction form as √3/2. it is noted that the value of sec 30 will be reciprocal of cos 30 value. cos 30 value cos 30 ...
If you have a triangle with no right angles, use the Law of Sines. According to Clark University, the Law of Sines is expressed in the equation sin(a)/A = sin(b)/B = sin(c)/C, where a represents an angle and A represents its opposite side. Step 2 To calculate the value of th...
Steganography is reasonably easy to implement yet difficult to detect, which is why threat actors use it to deliver malware, evade detection, and gain persistence.

Sine and cosine live on the unit circle (radius 1). The other functions use a radius of secant (tan/sec) or cosecant (cot/csc).Q3: What's the swapped function?We make a mini-triangle by shrinking the original triangle down, and rotating so dx matches the side of length 1. It ...
How are the angle of reflection and the angle of refraction related to the index of refraction? Calculate the net force in the vertical direction when the angle is 70.5° if the net force is 16600 N. How do you know when to use cosine, sine, or tangent for the normal force?
sine(x) = sin(x) = height of the screen, hanging like a sign cosine(x) = cos(x) = distance to the screen along the ground [“cos” ~ how “close”] the hypotenuse, the distance to the top of the screen, is always the same ...
Plan an investigation using the scientific method to investigate the factors affecting the period of the pendulum. Explain the meaning of confidence interval and give an example. Describe how to use Ohm's Law. Given the resistance and current how do you find the voltage, or ...
