### What is sin(x)+cos(x) in terms of sine? Socrati

sinx + cosx = Rsinxcos╬▒ + Rcosxsin╬▒. = (Rcos╬▒)sinx + (Rsin╬▒)cosx. The coefficients of sinx and of cosx must be equal so. Rcos╬▒ = 1. Rsin╬▒ = 1. Squaring and adding, we get. R2cos2╬▒ +R2sin2╬▒ = 2 so R2(cos2╬▒ +sin2╬▒) = 2. R = ÔêÜ2 Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.

Their usual abbreviations are Ôüí (), Ôüí (), and Ôüí (), respectively, where denotes the angle. The parentheses around the argument of the functions are often omitted, e.g., Ôüí and Ôüí, if an interpretation is unambiguously possible. The sine of an angle is defined.

The question asks for a sequence of transformations, so maybe it requires more than one transformation. Using sin (x+y) my first guess would be to make sin (y) and cos (y) equal1, so that I am.

Solve the equation sin x = cos x and then the inequality . sin x > cos x on the interval 0 x < 2.. From the unit circle we see that sin x and cos x can only have the same value in two places, in x = /4 and x = 5 /4 (45┬░ and 225┬░). The equation sin x = cos x can also be solved by dividing through by cos x sinX/cosX + cosX/sinX = secX cscX I've been thinking that in the end both sides should somehow end up with 1/(cosX)(sinX) but I really don't know how to do that since the left side has addition and not multiplication so maybe I'm wrong?

Occasionally it can help to replace the original variable by something more complicated Another easy way to convert sin to cos (and vice-versa): sin (x) = 1/3. just look at the fraction: take the denominator squared, minus the numerator squared and take the square root of that whole thing. Divide that by the original denominator and there you have your cosine. So: Sqrt (3^2-1^2) / 3. You can do these exact same steps to convert.

My professor has forbidden the use of the u substitution u=tan(x/2). I've tried multiplying the top and bottom of the integral by things like 1+sinx+cosx, sinx+cosx, sinxcosx, sin 2x, cos 2x, and a few others but I eventually get to a point where u-sub doesn't work out and I'm left with a sinx or cosx that doesn't cancel out µ£¼þ½ÖÕåàÕ«╣µØÑÞç¬õ║Äþ¢æÕÅïÕÅæÞí¿´╝îõ©ìõ╗úÞí¿µ£¼þ½Öþ½ïÕ£║´╝îõ╗àÞí¿þñ║ÕàÂõ©¬õ║║þ£ïµ│ò´╝îõ©ìÕ»╣ÕàÂþ£ƒÕ«×µÇºÒÇüµ¡úþí«µÇºÒÇüµ£ëµòêµÇºõ¢£õ╗╗õ¢òþÜäµïàõ┐ ### (sinx + cosx)/(sinx) - (cosx - sinx)/cosx = secxcscx - YouTub
