In trigonometry, cofunctions (sine and cosine, cosecant and secant, and tangent and cotangent) of __________________________ angles are congruent.
A) complementary B) right C) straight D) supplementary
Lemme give you an example that might reveal the answer to you,\[\Large\sf \sin(60^o)=\cos(30^o)\] 30 and 60 are what? Complimentary? Supplementary? ..?
thanks
ill try
You'll try after zepdrix attempts to help you? Basically gives you the answer?
complementary they make 90 degrees for same value
i mean ill try to know why is that answer
oh kk
|dw:1396120205469:dw|
simple minded way to see it \[\cos(\beta)=\frac{a}{h}=\sin(\alpha)\]
So someone spilled the beans already. :) 30 and 60 and `complimentary` angles. I was trying to show that the cofunctions(sine/cosine) of `complimentary` angles are equal to one another. Able to make sense of this?
