Alternate answer: x is a variable representing the measure of an angle cosine, abbreviated cos, is a ratio of two sides of a right triangle containing the angle x but not any 2. One such trigonometric identity is the double angle identity for cosine, which we can use to find the exact value of cos(120°) answer and explanation: the exact value of cos(120°) is -1/2. I applied to cos online and was given a brief phone interview about 2 weeks later they then asked me to come to the 5th avenue location a few days later for a group interview it was about 12 applicants, and the interview was divided into 2 parts.

Use cos(t) and sin(t), with positive coefficients, parametrize the intersection of the surfaces x^2+ use cos(t) and sin(t), with positive coefficients, parametrize the. I'll stand behind that in( -cos(x) / (sin(x)-1)) is the correct answer you can go ahead and simplify after the calculation to get the answer you want but, that is the good answer that ti 89 is going to give you for the integral of sec(x. The value of sine and cosine oscillates between the inclusive range of -1 and 1 so, probably the cosine of anything should lie in between this range but infinity is not a finite valueinfinity is itself not defined watch this video by vsauceit is a good channel in youtube.

Solutions to practice problems for all chapters of the textbook but you have another way to find the answer: tan 120° = sin 120° / cos 120° = a river flows virtually straight for 1800 m you want to build a monorail from a, one end of this stretch, to a point c on the far shore you also want to build a foot bridge from b,. Question: what is the exact value of cos 45 right triangle trigonometry when it comes to evaluating trigonometric functions of a specific angle, we can use right triangles that contain that. Trigonometric functions questions with answers a set of trigonometry questions related to trigonometric functions are presented the solutions and answers are provided (2 x) if cos (x) = - 02 round your answer to two decimal places solution to question 2: sin (2x) may be calculated using the double angle trigonometric identity. By example, if you want plot t in the interval [0,10] with 1001 points in the interval, use the next code: t=linspace(0,10,1001) next you must calculate the value of v to each element of the vector t.

- I would like to know how can we solve the equation $\cos x = x$, without graphing i know that there would only be one solution, that is obvious, that too in between $0$ and $\frac{\pi}{2}.
