What is cosine 0?
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
What is the domain of the cosine function?
-1<cosine<1
What is the formula for the y-intercept of a cosine function?
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
What is the cosine of 0.57?
The cosine of 0.57 degrees is 0.999951. The cosine of 0.57 radians is 0.841901
What is cos42?
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
What is the effect of the phase angle phi on the cosine function cos(wtphi)?
The phase angle phi in the cosine function cos(wtphi) affects the horizontal shift of the graph of the function. A positive phi value shifts the graph to the left, while a negative phi value shifts it to the right.
What is a correction factor capacitor?
i know that static capacitors are used to improve the power factor. power factor should be high. Static capacitor supplies lagging reactive power. That means; the current I has 2 components they are magnetising Im (watless or waste current) and useful current Iw. Iw is in phase with voltage and Im is 90 degree away. Phase angle between them is phi 1. power factor is given by cosine of phi 1. phi angle should be less so that cosine of phi is high. To make phi angle less we use capacitor; this is nothing but power factor correction and capacitor used for this is called power factor correction capacitor. now when a capacitor is connected, it induces a current Ic 180 out of phase from Im and less in magnitude from Im. therefore, now the magnetising current is Im1=Im-Ic. due to this the phase angle reduces to phi 2. now the new power factor is cosine of phi 2. it is improved power factor.
What is cosine cubed?
It is cosine*cosine*cosine.
Phi phi intersection phi equals phi a true statement?
phi
What is the cosine of 3.14?
what is the cosine of 3.14 ?
What is cosine of 1?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
What is the cosine of 6 degrees?
Cosine is 0.995
What is an inverse cosine?
The inverse of the cosine is the secant.
Reciprocal of a cosine?
Reciprocal of Cosine is Secant
What is the cosine of -90?
Cosine of -90 is 0.
What a sentence for cosine?
Cosine is a trigonometrical function.
