Problem with Shift Solve, SOLVED!

[@exequielviacrusis4694]

sir i have an issue with my calculator, when shift solving for trig functions such as cos(x)=0 it gives me of x values very large but are divisible by 90, though its not much of a problem on this example its very annoying when it comes to larger functions such as cos(x)+6cos(2x)=0, any idea how to fix this, I always set my trial value to zero

Sir good day, kasali po ba sa board exams ang National Building Code, like are there questions "what is the minimum area for a toilet"?

[@perfectopadillajr3452]

Rarely. Usually, thats the scope of Archi Brd Exam.

So Sir what are the things that are needed to be memorized? I'm referring to terminologies and definitions, not formulas for problems solving. I am a second year student sir and want to start early with the memorization so that I can focus on problem solving later in the review for board exam.

@@philipamerjacobcinco4300 Dont focus on the terminologies. They are only about 5% to 10% of the board exam. Terminologies are anything under the sun. But most of them, lumabas sa special sessions namin before the board exam. (product of our research work). Focus on computations and absorb terminologies along the way.

Sir ask po. Why po iba iba result pag shift solve ko. Equation: 6^x(9^(x+2))=13^(x+5) minsan 13 or 15 po pero 7.91 ang correct answer ng guro ko

None of those values is correct. Pls try to substitute and prove them wrong. -5 is the right answer.
