I need to find the function average and root mean square. I have the answer and the formulas. Can you give me a step by step solution?

T1 Find out the average and RMS value for the signal above, as uo = 4 V, Ti = 70 ms ja T2 = 84 ms. Give your answer with TWO DECIMAL PLACES! = 1.81 V (TWO DECIMALS!) Your last answer was interpreted as follows: 1.81 Average value is incorrect. Marks for this submission: 0.00/1.00. Urms = 19.06 V (TWO DECIMALS!) Your last answer was interpreted as follows: 19.06 RMS value is incorrect. Marks for this submission: 0.00/1.00. A correct answer is 3.33, which can be typed in as follows: 3. 33 A correct answer is 3.65, which can be typed in as follows: 3. 65 Average value of a function fave b - a f ( x ) dx d+1 fave = T f(x) dx cd+T frms = If (x)]2 dx . If the function is periodic with period T, then This formula is needed, when calculating RMS value for different d+1 alternating voltages, such as frms = If (x)]2 dx triangle wave or sinusoidal wave. - IF In which the d can be chosen as wanted (quite often the easiest integration is obtained when d = 0.) . If a periodic voltage applied to a resistor is u = u(t) then the heat formed is the same as having a DC voltage of Urms applied to the resistor
