Permutations
In Triangle ABC, AC = 3cm, BC = 2cm, ∠BAC = θ and ∠ABC = 2θ. Calculate the Value of θ? I used the Sine Rule to get the ratio of Angles to 2/3, but not sure how else to proceed. Thanks.
Where is tan(xy) continuous? I know that it is odd multiples of pi/2, but what is the reasoning behind that? Any help would be much appreciated!
6cosxsinx - 3cosx - 4sinx + 2=0 for exact solutions in the interval x is more than or equal to 0 and less than or equal to 360°. I've got it down to 3cosx-2 = 0 or 2sinx-1=0...
Find the radian measure of the central angle of a circle of radius 96 km that intercepts an arc of length 294 km. Answer in units of rad
=(sinx/cosx - sinx)/ (2sinx/cosx) = sinx-sinxcosx/cosx • cosx/2sinx = sinx (1-cosx)/2sinx = 1-cosx/2 now im lost help!!
This is a precalculus question involving right triangle trigonometry
Using only the double angle identities how to solve for this? im stucked after 2cos^2 (2x) -1
If cos £ = -4/9 with £ in Quadrant II, find sin £.
I know that i should multiply something to it for it to become 2sinAcosA for me to be able to solve it. Unfortunately, if i multiply2/2 to it will just become 2/16 that will just bounce back to 1/8...
A bicycle tire has a diameter of 24 inches and is revolving at a rate of 10rpm. At t=0, a certain point is at a height of 0. What is the height of the point above ground after 3 seconds?
i know that cos(a-b) = cosacosb+sinasinb And cos(a+b) = cosacosb-sinasinb and cos(x+x) = cos^2x-sin^2x
