at -90 degrees the value of cos(x) is 0.
Cos 90=0 because cos@=base/hyp and at 90degree base becomes zero since zero divided by anything is zero. RPHK_Haider...
The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.
hi,the value of cos 60 is 1/2
-5
at -90 degrees the value of cos(x) is 0.
The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
Assuming you mean -90 degrees, not radians: tan (-90) = [sin(-90)]/[cos(-90)] = (-1) / 0 You cannot divide by zero. tan (-90) is undefined/does not exist.
Angle between v and i is 90 deg so, cos 90 = 0 Same for pure capacitor
sin θ = cos (90° - θ) cos θ = sin (90° - θ)
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
Cosine of 90 degrees is zero.
Cos 90=0 because cos@=base/hyp and at 90degree base becomes zero since zero divided by anything is zero. RPHK_Haider...
The value of cos 40 degrees is approximately 0.766.
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
