Web18. apr 2024. · to solve for x, you should first understand when cos(x) is negative - cos(x) is negative when the angle x is in the 2nd and 3rd quadrants. value of cos(x) is sqrt3/2 for cos(30 degrees) or cos(pi/6) Let’s consider an angle in the 2nd quadrant which has a reference angle of 30degrees - it would be . 180-30=150degrees . or pi-pi/6= 5pi/6 Web28. mar 2016. · Isolate the angle 2x, by following the reverse "order of operations". Step 1: Add 1 to both sides: 2cos^2(2x)=1 Step 2: Divide both sides by 2: cos^2(2x) = 1/2 Step 3: Take the square root of both sides: cos(2x) =(sqrt(2))/2 or cos(2x) =(-sqrt(2))/2 (don't forget the positive and negative solutions!) Step 4: Use inverse of cosine to find the angles: 2x …
Web04. okt 2024. · sin(x) has a range of -1 to 1, so we need to find the values of x that give -1 and 1. Using traditional trig memorization of values, we have the following: maximum value is at x = Pi/2. minimum value is at x = 3Pi/2. Let me know if you have questions on this. If you're set with it, thanks in advance for a five star rating! Thanks again!-Scott WebAlternatively, one can note that C is a level set of the function f(x,y) = 4x2 +y2, defined on all ofR2.
