Solve 2tan^2x + 1 = 0 Interval : [0, 2 pi]
Determine approximate solutions for this equation in the interval x is all real numbers [0, 2pi), to the nearest hundredth of a radian: cosx + 0.75 = 0
A painted dot on the circumference of the wheel is 12cm from the centre of rotation of the wheel. How far does the dot travel in 5 sec., to one decimal place?
Show that tanx = sinx / cosx can be written as tan(x+y) = (tanx + tany) / (1 - tanxtany)
The manufacturer of a propeller for a small aircraft mandates a maximum operating angular velocity of 300 rad/s. Determine whether it is safe to install this propeller on an aircraft whose engine is expected to run at a maximum of 2800 rpm.
What is the exact value for sin5pi / 12 ?
Prove that: 2sinxsiny = cos(x-y) - cos(x+y)
Show that tanx= (sinx/ cosx) can be written as: tan(x-y) = (tanx - tany) / (1+ tanxtany)
The London Eye is a large ferris wheel. Each sealed and air-conditioned passenger capsule holds about 25 passengers. The diameter of the wheel is 135 m, and the wheel takes about half an hour to complete one revolution. a) Determine the exact angle, in radians, that a passenge...
You would multiply the top one by -4 and the bottom one by +3, if you want to keep y positive.
