5tanx + 5= 2/cos^2(X).

answer is, 71.6°, 153.4°, 251.6° and 333.4°.

please help. thankyou!! :)

as stated. thankyou! :)

answer is 112°, 248°.

hey guys! this is my question and i did it but, i can only find these 3 answers(it is correct). but, there is another answer that i do not know how to get it, the other answer is 3.2°. please look at my steps and tell me why i couldn't get it, and give your steps and explanation on how to get the 3.2°. please help and thankyou! :)

tan(2y-85°) = -5

basic angle = 78.7°

2y-85° = 101.310°, 281.310°,461.310°

2y= 186.31°, 366.31°, 546.31°

v= ____? 93.32°, 183.2°, 273.2°,

Hence, solve the equation 4t^3 + 3t^2 - 12t - 1 = 0.

please help me! steps and thank you in advance! :)

please help, and steps please! thank you in advance! :)

cos3x+2cosx=0

cos3x-cosx=-3cosx

thankyou! explain please.

answer is π/3, π/2, 2π/3. steps please, thankyou.

actually, you just have to show me how you use cos3x-cosx=-4sin^2(x)cosx to change to cos3x+2cosx=0 :) its not necessarily to solve it for me, i'll do it myself :)

um, heres one, but i don't understand, you can explain this to me or you give me your own steps and explain it. thankyou! here:

cos3x+2cosx=0

cos3x-cosx=-3cosx

that's all. i just dun get the part ^ how you get the -3cosx from? please help! :)

as stated, thank you :D

thanks in advance! :D

The electronic balance we use in the lab gives its measurements in the unit, g (grams), which is the unit for mass.

But does an electronic balance measure weight or mass? Explain why.

If it measures weight, would it be possible to re-design the electronic balance such that it measures mass, or vice versa? Describe how you may do it.

Thanks, and i appreciate it if you could help me out here :)

Simplify the following and express as a single logarithm.

2lg(x+2)+lg(x+1)-lg(x^2+3x+2)

Find y in terms of x.

2log_3y-4=3log_3(x+2)

Solve for x.

a) 2lg5-lg(x+2)=1-lg(2x+1)

b) log_3(x+2)+log_3(10-x)-3=0

c) lg(20x)-lg(x-8)=2

fyi, log_3 is log base 3.

i'm stuck, so please help me if you know,

even if it's one question.

thanks a lot :D

solve the following equation.

3^x.10^2x = 4.20^x-2

by using appropriate substitution or otherwise, solve the following equation.

2e^x = 7√e^x - 3

thanks a lot! :)

Alright, I really don't understand much about the sphere grids and stuffs. I played till the end sometime ago, but all my characters seems to be damn weak compared to others. I finished the upgrading of the sphere grid till the end for each character, but I didn't unlock those Level. 1/2/... Spheres. I didn't unlock them because I don't have all those Level. 's Spheres, is it hard to obtain it? Please do help out here, it would be great if you tell me where to get all those Level. 's Spheres easily and those stats like, defense, strength, magic, etc. that best matches for each of the character. It would also be great if you tell me all that I need to know about sphere grids and all those spheres, ... . (;
