Hey guys please help? Trigonometry
So, the task is: find cos a, if:
1) sin a = (3β11)/10, a β (0; Ο/2)
2) sin a = (3β11)/10, a β (Ο/2; Ο)
Could someone please explain how to solve it? I can't figure out what difference a β (0; Ο/2) and a β (Ο/2; Ο) make in the way I have to solve it mmh... I'll pin my attempt to do the first one (failed for some reason)

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
