Without going into a large Calculus based proof, if two angles of projection are complementary (add to 90 degrees) then the ranges are the same. A 45 degree angle yields the greatest range, but 40 degrees and 50 degrees would yield the same range, so would 30 degrees and 60 degrees. Similarly, 0 degrees and 90 degrees would also have the same range (a range of zero, that is).
At 45° angle.
45 degrees
It ranges between 180 and 360
an obtuse angle is an angle ranging from 90 to 180 degrees. an acute angle ranges from 0 to 90 degrees. so to answer your question. obtuse.
Cosine cannot have this kind of high value, it ranges from -1 to +1
water is projected from two rubber pipes at the same speed from one at angle of 30 and from the other at 60 why are the ranges equal
w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
At 45° angle.
45 degrees
.7
It ranges between 180 and 360
Its Azimuth
The submerged angle of repose of sand refers to the maximum angle at which submerged sand particles can stack up without further movement or slumping. It typically ranges from 25 to 37 degrees depending on factors like grain size and water content.
an obtuse angle is an angle ranging from 90 to 180 degrees. an acute angle ranges from 0 to 90 degrees. so to answer your question. obtuse.
a constant horizontal speed
I can only use an EX: if you have a flashlight and shine it at a mirror, it will then be projected at an angle, like on the celling. that is the bending of light.
First angle projection is the one in which the object is placed in the first quadrant and views are projected on the planes. Refer this link for illustration and symbol http://www.technologystudent.com/designpro/ortho1.htm
