What is the value of cosx at -90?
at -90 degrees the value of cos(x) is 0.
Sin30 cos90 sin 90 cos30?
To simplify the expression sin(30°) cos(90°) sin(90°) cos(30°), we first evaluate the trigonometric functions at the given angles. sin(30°) = 1/2, cos(90°) = 0, sin(90°) = 1, and cos(30°) = √3/2. Substituting these values into the expression, we get (1/2) * 0 * 1 * (√3/2) = 0. Therefore, the final result of sin(30°) cos(90°) sin(90°) cos(30°) is 0.
How cos 90 is 0?
Cos 90=0 because cos@=base/hyp and at 90degree base becomes zero since zero divided by anything is zero. RPHK_Haider...
What is the value of Cos 1?
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.
What is cos 60?
hi,the value of cos 60 is 1/2
What is the value of cosx at -90?
at -90 degrees the value of cos(x) is 0.
What trigonometric value is equal to cos 62?
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°.
What is the value of tan -90?
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.
What is the value of power factor for a pure inductor?
Angle between v and i is 90 deg so, cos 90 = 0 Same for pure capacitor
What is the relationship between the cos and sin of the non 90 degree angles in a right angle triangle?
sin θ = cos (90° - θ) cos θ = sin (90° - θ)
Why is sine 30 the same as cosine of 60?
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
Cos square 90-x equals?
Cos(90 - x) = sin(x) so cos2(90 - x) = sin2(x)
What is cos 90?
Cosine of 90 degrees is zero.

What is the value of cos 40 degrees?
The value of cos 40 degrees is approximately 0.766.
What is the value of the cos of 34 degrees?
cos 34o ≈ 0.829 cos 34 = 0.86074
