15(pi/4) is a multiple of pi/4. remember a unit circle is 2pi. In this case, 8pi/4 = 2pi. 15-8 =7, so we ...

You can put this solution on YOUR website! Convert to degrees by multiplying the given angle by 180/pi ((15pi)/4)*(180/pi) = (15pi*180)/(4pi) = (2700pi)/(4pi) = 675

multiply both sides of this equation by 15/pi to get: 15/pi * -1.570796327 = t - 7.5 simplify to get:-7.5 = t - 7.5 solve for t to get: t = 0 that is correct and is now in line with what is stated in the …

You can put this solution on YOUR website! this function is periodic in with period (ie one wavelength) so, the "primary interval for this equation" is units

Question 884441: Find a cofunction with the same value as the given expression: cos pi/15 This is what I have come up with so far...

For your problem theta 15(pi/180) radians, so the arc length is (15)(pi/180)*40 = 3.3333... cm ===== 2. Find the distance traveled by the tip of 7 cm min. hand of a clock in 7 and 1/2 min. --- …

You can put this solution on YOUR website! Find cos(15pi/4) 15π/4=3π+3π/4 This equals to a reference angle of π/4 in quadrant IV in which cos>0

You can put this solution on YOUR website! the best way to remember this kind of stuff is to consider units. Radians are measured in "pi" units so to speak, so if it were times 180/pi it …

Question 1114729: Hi I understand the formulas of circumference and diameter and whatnot, I have 2 homework questios and I don’t seem to fully understand it:

C = 2*15*pi = 30pi inches per rev @ 800 rpm, that's 24000pi inches/minute = 2000pi ft/minute = 120,000pi ...
