Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,
Hence, this is the required solution.
Answer:
Yes please and thanks for the points!
Step-by-step explanation:
have a great day!
The pattern is multiply by 4. so the next number is 4096
Answer:
Katie
Step-by-step explanation:
Use seconds as the standard unit to compare the speeds of the 4 runners
Tony is already in standard form and runs 12 ft/s
Katie:
450/30
15 ft/s
Frank:
1 mile = 5280 feet
5280/577
9.15 ft/s
Adam:
I minute = 60 seconds
880/60
14.67 ft/s
A) 5:00
<span>At 00 minutes, the minute hand is point straight up. That is one quarter turn of the entire circle. One-fourth of 2π radians is 1/2 π, or π/2 </span>
b) 7:15
At 15 minutes, the minute hand is pointing straight to the right, along the imaginary positive x-axis, so it has turned through none of the circle. 0 radians.
c) 3:30
<span>This one isn't as clean as the others. Let's first find the 35 minute position: it occurs at hour number 7. Identify that measuring from 3 (positive x-axis, measuring counter clockwise) you have to turn through 40 minutes worth of clock. 40 minutes represents 40/60 of an entire clock, which reduces to 2/3. 2/3 of all the radians in a circle (2π of them) is 4/3π, or 4π/3.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
