I have the problem of $\arcsin(\sin(\frac{5\pi}4))$. I went to solve this by first finding the reference angle because $\frac{5\pi}4$ is not in the domain of $\arcsin(\sin(x))$. since $\frac{5\pi}4$ is in quadrant III, that would be $\frac{5\pi}4 - \pi$, which is equal to $\frac{\pi}{4}$.

Pi symbol meaning. Pi symbol sign π, pronounced in English as pie sign is a mathematical constant that is the ratio of a circle's circumference to its diameter. It has been represented by the Greek letter "π" since the mid-18th century. Pi π is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers; consequently, its decimal representation never ...

Example 1: Special case, Duty Cycle = 50%. Consider the case when the duty cycle is 50% (this means that the function is high 50% of the time, or T p =T/2), A=1, and T=2.In this case a 0 =average=0.5 and for n≠0: $$\displaylines

Jul 23, 2016· You use the formula for the sine of a sum: #sin(a+b)=sin a cos b+cos a sin b#. Think of a pie divided into twelve slices. Three of them form one quarter, two more form one sixth of the pie.

Jul 02, 2016· sin(pi/5)=sqrt(10-2sqrt5)/4 Let theta=pi/5, then 5theta=pi and 3theta=pi-2theta. Note theta) is an acute angle. Hence sin3theta=sin(pi-2theta) but as sin(pi-A)=sinA This can be written as sin3theta=sin2theta expanding them or 3sintheta-4sin^3theta=2sinthetacostheta as theta=pi/5 we have sintheta!=0 and dividing by it we get 3-4sin^2theta=2costheta or 3-4(1-cos^2theta)=2costheta or …

The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5.It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property.This number appears in the fractional expression for the golden ratio.It can be denoted in surd form as: . It is an irrational algebraic number.

The Canakit 2.5A supply crosses 2.5A at about 4.5V (2.5*4.5 = 11.25W). Both of these are well below 5V. Probably high enough that the RPi won't crash, but cutting it close. Another interesting point is where the curves cross 5.0V. The Kootek 2.0A supply crosses 5.0V at about 0.8A (0.8*5.0 = 4.0W).

$\begingroup$ How is this a quadratic equation of the form $2x^2-x-1=0$ exactly? It seems to me that your main equation is merely what you get when you put the double angle formula relating $\cos\frac\pi5$ and $\cos\frac{2\pi}5$ into the LHS of what we want to be $\frac12$.

The Stefan–Boltzmann constant (also Stefan's constant), a physical constant denoted by the Greek letter σ (sigma), is the constant of proportionality in the Stefan–Boltzmann law: "the total intensity radiated over all wavelengths increases as the temperature increases", of a black body which is proportional to the fourth power of the thermodynamic temperature.
