How do you find sec on TI-83 Plus?
There isn't a sec key on the TI-83 Plus. Secant is 1/cosine, which is what is used to find secant on a TI-83 Plus. For example, to find the secant of 4, enter 1/sec(4).
Tan theta plus cot theta equals 2csc2 theta?
Yes, it is.
Sec squared theta plus tan squared theta equals to 13 12 and sec raised to 4 theta minus tan raised to 4 theta equals to how much?
It also equals 13 12.
How do you solve without a calculator tan squared theta plus 1?
This is the same as secant squared theta [sec²(Θ)].Take the identity sin²(Θ) + cos²(Θ) = 1Divide both sides by cos²(Θ):sin²(Θ) / cos²(Θ) = tan²(Θ)cos²(Θ) / cos²(Θ) = 11 / cos²(Θ) = sec²(Θ)tan²(Θ) + 1 = sec²(Θ)
How can you verify 1 plus tan theta divided by 1 minus tan theta equals cot theta plus 1 divided by cot theta minus 1?
It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.
How do you prove cot squared theta plus cos squared theta plus sin squared theta scs squared theta?
Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.
When does co secant equal -1?
cosecant(x) = 1/sin(x) = -1sin(x) = -1x = 270 degrees(plus or minus any whole multiple of 360 degrees)
How do you verify cos2 theta divided by csc2 theta plus cos4 theta equals cos2 theta?
Using x instead of theta, cos2x/cosec2x + cos4x = cos2x*sin2x + cos4x = cos2x*(sin2x + cos2x) = cos2x*1 = cos2x
Find theta if theta is 0 deg theta 360 deg and 2 sin theta plus 1 equals 0?
2 sin (Θ) + 1 = 0sin (Θ) = -1/2Θ = 210°Θ = 330°
What is theta when tantheta plus sectheta equals 1 please show work?

If tansqtheta plus 5tantheta0 find the value of tantheta plus cottheta?
tan2(theta) + 5*tan(theta) = 0 => tan(theta)*[tan(theta) + 5] = 0=> tan(theta) = 0 or tan(theta) = -5If tan(theta) = 0 then tan(theta) + cot(theta) is not defined.If tan(theta) = -5 then tan(theta) + cot(theta) = -5 - 1/5 = -5.2
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
