let abc be the triangle with base bc. Consider it is equilateral triangle.. Now draw ad perpendicular to bc. Now ad equalls dc. Now tan 60 degree equalls ad/dc. With value of tan 60 and ad we can find dc. There fore bc equalls 2 * dc
This is the image
DC stands for Diamond Cut.
a/b=c/d =>ad=bc =>a =bc/d b =ad/c c =ad/b d =bc/a so if a+b=c+d is true => (bc/d)+(ad/c)=(ad/b)+(bc/a) => (bc2+ad2)/dc=(da2+cb2)/ab => ab(bc2+ad2)=dc(da2+cb2) and since ad=bc, => ab(adc+add) =dc(ada+adc) => abadc+abadd =dcada + dcadc => abadc-dcadc =dcada-abadd => (ab-dc)adc =(dc-ab)add ad cancels out => (ab-dc)c =(dc-ab)d => -(dc-ab)c =(dc-ab)d => -c = d so there's your answer :)

No.
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Variable frequency Drive is not compatible with a DC Motor. VFD can be used only with AC motors, where frequency plays a key role in defining the speed of the motor.
Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid. "zhuge fs"
Dc is used to power an oscillator circuit of which the frequency can be controlled such as 60 HZ.
Transformers are used in AC circuits and won't work for DC. A frequency of 60Hz is popular in the USA.
A: Sometimes a spectrum of frequency must be analyzed a voltage to frequency converter can be used to sweep a range of frequency just by changing some DC level.
DC has no frequency.

dc does not have frequency only ac
A synchronous motor is used only with a.c. Its speed is dependent on the frequency of the a.c.
