Integrate (√x - sinx/2 cosx/2+5) dx |
|
Answer» Answer: D = C - 1/2 Step-by-step explanation: All answers show you a METHOD by using sin(2x) = 2sin(x)COS(x) However, you can also SOLVE it by using substitution and the property that d(sin(x)) = cos(x) dx. Substitute sin(x/2) = t. Hence, d(t) = 1/2*cos(x/2)d(x) Therefore, the integral becomes easier i.e., Int of 2*t*d(t) Int. 2*t*d(t) = t^2 +C = (sin(x/2)) ^2 +C Since, cos(x) = 1 - 2*(sin(x/2)^2) And “C” can be written as any constant, i will just take the value of half from it (sin(x/2)) ^2 +C = 1/2 - cos(x) /2 + D, where D = C - 1/2 Remember, when using substitution, also update the limits. I hope helps to you |

Find the greatest number of 5 digit exactly divisible by 2‚4‚6‚8‚10. |
Answer» Good Morning My Dear FRIEND, here is the answer to your question..We know that the LCM of 2,4,6,8,10 = 120 Now, if 120 divides that number this means that the number is also divisible by 2,4,6,8,10 so, greatest 5 digit number = 99999 Lets check that 120 divides 99999 We can clearly saw that 120 don't divides 99999 completely..it LEAVE a remainder of 39 This means that 39 is extra in 99999 to become the multilple of 120 therefore , lets subtract 39 from 99999 to remove the extra 39 99999 - 39 = 99960 Now, 99960 is divisible by 120 Therefore, the greatest 5 number which is divisible by 120 =99960 Hope my answer HELPS you..Please dont forgot to hit the thanks button and also MARK my answer as brainliest and be my followerThanks |

temperature of a place at 4am was 3°. temperature increases by 1° in the first hour and decrease by 2° in the second hour. what was the temperature at 6am |
|
Answer» Answer: At 12 noon, the TEMPERATURE =10°C above zero The temperature is decreasing at 2°C per hour 8°C below zero =−8°C So, total fall in temperature from 10°C to 0°C and from 0°C to −8°C=18°C Since the temperature falls 2°C in every ONE hour. Therefore, to decrease 18°C, time TAKEN = 18/2 = 9 hours Present time is 12 noon so, the time when the temperature is −8°C =12noon+9hours So, The time at which the temperature will be −8°C=9PM At 9 PM, the temperature is −8°C, the temperature at 12 midnight will be = (−8°C)+(−2°C×3hours) =(−8°C)+(−6°C) =−14°C So, at 12 midnight the temperature will be−14°C. |
