find the value of pi in the following: sin pi=cos(pi + 40) sin(80 - pi)=cos pi your kind input is appreciated. |

Is that pi meant to be teta as in angle or pi as in 22/7 or 3.142? |

@telz, it is meant to be 22/7 |

Sure? Then commonsensically,22/7 is your answer. Hmm the question doesn't seem right though. Hope you know that the rate at which sin increases is equal to the rate at with cos decreases(in layman's terms). What i mean is that sin1 = cos99,sin2 = cos88 and so on. I think the question isn't correct sha,to my knowledge of trig. I actually think its sin pi=cos(90-pi) and sin(90-pi)=cos pi. What do you think? |

@telz, my bad. The pi is supposed to be teta. I am not really a math person and i cant wait to get to 200 so i can drop this load. |

No problem,do you mean 200 in jamb or 200 level. Maths isn't so hard  . If you got anymore questions,i'll be glad to help cos i'm writing Jamb this year. |
