Aug 13, 2010 · I have trouble doing this problem. The problem: Let tan β= 6 Find tan(90°-β). Please and thank you.

What is the sine, cosine, tangent, cotangent, cosecant, and secant of -90 degrees?

Nov 12, 2013 · tan (90 ∘) is not defined. That is why you were told to use the sum of angles formulas for sine and cosine, not the sum of angles formula for tangent.

Mar 26, 2018 · Please see below. sin (-90^0)==-sin90^0=-1 cos (-90^0)==cos90^0=0 tan (-90^0)==-tan90^0= undefined csc (-90^0)==-csc90^0=-1 sec (-90^0)==sec90^0= undefined cot …

Apr 29, 2018 · Given that cosx=p Where x us an acute angle in degrees find in term of p i) Sin x ii)tanx iii)tan (90-x)?

Jan 6, 2018 · Can anyone see an easy way to explain why tan 89.9 is approximately the same as 10x tan 89? Just messing around on the calculator and they are remarkably close..

Jun 27, 2018 · We usually meet them in right triangles, where trigonometric functions are usually more familiar. As such, let x and y be the acute angles of a right triangle with sides a,b,c. tanx …

Jun 10, 2016 · We know that tantheta=cot (90-theta) hence tan (5x+11)=tan (90- (6x+2))=>5x+11=90-6x-2=> 11x=90-11-2=>11x=77=>x=7

Jul 26, 2018 · f (x) = tan(2x) is the function f (x) = tan(x) stretched by a factor of 1 2 parallel to the x axis. Since the asymptotes of tan(x) are 90∘,270∘,450∘ etc. , the asymptotes of tan(2x) will …

Feb 22, 2009 · As θ approaches 90 degrees, the "near" gets shorter and shorter: c o s (θ) goes to 0. As to your refernce to tangent and secant: both of those have cosine in the denominator …
