sin(x+y)/sin(x-y)=(a+b)/(a-b) then tanx/tany=?
A surveyor determines that the angle of elevation to the top of a building from a point on the ground is 26.2 degrees. He then moves back 53.9 feet and determines that the angle of elevation is 18...
Cos2 (2x) - cos2 (6x) = Sin(4x)sin(8x)
Sin2 (6x) - Sin2 (4x) = sin(2x)Sin(10x)
I'm not asking what it does, and I'm not looking for "tan(angle)=opposite leg/adjacent leg". I'm asking what the actual function is. For instance, using degrees (not radians) tan(22.5)=20...
I am not havin g any idea to solve it.
please help me soon
if secA=17/8 and cosecB=5/4 then sec(A+B) can have value ?
I just need help. If someone could give me the answer as well as explain it, that would be amazing
Help me and show work please :)
show work please and explain it please so i can understand
Convert 210° from degrees to radians. Use the value of p found on a calculator and round answers to four decimal places, as needed.
