Find an exact value for cosec (\frac{11\pi}{12}). Let (4, 3) be a point on the terminal side of \theta. Find the exact values of \cos \theta, \csc \theta, and \tan \theta. An angle \theta has \sin \theta= \frac{35}{37} and terminal side in the second quadrant...
解析 cosec x=-2It is known thatcos ec =2∴cos ec =-cos ec =-2 and cos ec =-cos ec =-2i.e.,cos ec =-2 and cos ec =-2Therefore,the principal solutions are x= and .Now,cos ec x=cos ec ,where n∈ZTherefore,the general solution is ,where n∈Z ...
Using the formula, where nn is the number of observations (77 in this case): (7+12)th=4(7+12)th=4. The 4th4th value in this sorted list is 15–––15_, so the median age of the students is 15 years old––––––––––––15 years old_. Example 3: Imagine you have ...
